Ferguson, who plays Lucas' sassy (and almost always correct) little sister Erica Sinclair, is the youngest member of the main cast at 19. She was 11 when she joined "Stranger Things" in season two.

Impressively, while she was shooting the show, she was also balancing her studies — she graduated from high school this year. She wrote to her 3.7 million Instagram followers that "balancing an adult career — on and off screen" while maintaining an above-average GPA at her public high school was a "unique journey."

Besides playing Erica, Ferguson had roles in the films "The Oath" and "The Curse of Bridge Hollow" (another Netflix joint). She's also had voice roles in animated series "Hamster & Gretel" and "My Dad the Bounty Hunter."

Now she's done with school and has more time to focus on her career, we expect Ferguson will appear in more scene-stealing roles. In fact, she already booked a role in the coming Jean-Michel Basquiat biopic "Samo Lives."

Heaton, 31, plays Jonathan Byers, Will's devoted older brother who will do anything to help Will and his mom. He was 22 when the show began, playing a high school sophomore.

The British actor hasn't done much outside the show. He was in the calamitous final 20th Century Fox "X-Men" movie, "The New Mutants," in 2020, which essentially doesn't exist. He also starred in the indie movie "No Future," which never had a wide release, and "The Souvenir Part II," which was critically beloved but not a big box-office hit.

On the TV front, he only appeared in an episode of the 2020 anthology series "Soulmate."

And while he has 5.5 million followers on Instagram, that number doesn't compare to some of the follower counts of his fellow cast members.

We'd argue that Heaton's biggest claim to fame is his real-life relationship with Natalia Dyer, his on-screen love interest.

Speaking of Dyer, 30, she's next up on the list. She plays Nancy Wheeler, Mike's older sister with an investigative streak. Nancy was also involved in a love triangle with her first love, Steve, and Jonathan. She eventually picked Jonathan, but some moments in season four made it seem like a possible "Stancy" reunion is in the cards.

Dyer, who was 21 when the show began, has the edge on her boyfriend, Heaton. She's appeared in multiple short films during her "Stranger Things" tenure, and had supporting roles in films like "Velvet Buzzsaw" and "Things Heard & Seen" (both Netflix films).

She also had a lead role in the coming-of-age indie "Yes, God, Yes," released in 2020. But it's been five years, and she hasn't been able to parlay that into more leading roles.

In 2023, she starred in the first season of the Peacock series "Based on a True Story" alongside Chris Messina and Kaley Cuoco.

Dyer has slightly more Instagram followers than Heaton as well, at 8 million.

Montgomery was 23 years old when he joined "Stranger Things" in season two as Max's older stepbrother, Billy Hargrove, who made it his personal mission to bully Max, her friends, and even Steve.

Now 31, Montgomery has been steadily working, but hasn't gotten his true big break. The same year he joined "Stranger Things," he starred in the ill-conceived "Power Rangers" movie as the Red Ranger.

Since then, he had a small role in "Elvis" and starred in the underrated 2020 rom-com "The Broken Hearts Gallery."

However, Montgomery has big things coming soon. He has four movies on the docket: "Faces of Death," which costars Barbie Ferreira, Josie Totah, Charli XCX, and Jermaine Fowler; "Dead Man's Wire," which will be directed by Gus Van Sant and costars Bill Skarsgård, Colman Domingo, Myha'la, and Cary Elwes in January 2026; and "The Engagement Party" which will also be Montgomery's directorial debut.

But since those projects haven't come out yet, he can't be too high on this list.

The Australian actor has 7.7 million followers on Instagram.

Franco joined the cast in the fourth season of "Stranger Things" as Argyle, Jonathan's stoner best friend in California, though he's missing from the show's final season.

Before even joining the show, 31-year-old Franco was well on his way to becoming a zillennial "that guy" — he's had recognizable roles in projects like "Booksmart," "Superintelligence," "Self Reliance," "American Vandal," and "Y2K" just last year.

Franco also has had successful voice roles. He starred in "Ruby Gillman, Teenage Kraken," and has been playing DJ Catnip on the hit children's show "Gabby's Dollhouse" since 2021. A feature-length "Gabby's Dollhouse" film premiered in October, with Franco reprising his role. He has another voice role in "Goat," which premieres in February 2026.

He'll be (physically) back on our screens in November 2026 with "Focker In-Law."

His social media is what takes him down a bit, with 573,000 followers on Instagram.

Schnapp, 21, has played Will Byers, who was originally taken to the Upside Down (a dark parallel universe) in the show's first episode, since he was 12.

Pre-"Stranger Things," Schnapp had a small role in "Bridge of Spies" and played Charlie Brown in "The Peanuts Movie."

Since playing Will, Schnapp had a small role in "Hubie Halloween" (a Netflix movie) and starred in the indie film "Waiting for Anya," both in 2020. In the five years since, he's had just one other role, appearing in the 2023 thriller "The Tutor," which was a flop critically and financially.

There's a reason for his slowdown in work, though — since 2022, he's attended the University of Pennsylvania. He's also leveraged his fame to become a business owner (he started the company TBH, which is a healthier alternative to spreads like Nutella) and YouTuber. He has 4.53 million subscribers on the site, even though he hasn't posted in years. He also has a huge Instagram presence, with 22.9 million followers.

Schnapp has mainly been in headlines for his views on the Israel-Hamas conflict. Per Entertainment Weekly, after he made posts that were interpreted as him supporting Zionism in 2023, some fans called for a boycott of season five (which was then in production) or for Schnapp to be fired.

In a January 2024 TikTok post, he said, "I feel like my thoughts and beliefs have been so far misconstrued from anything even close to what I believe."

He continued, "I think anyone with any ounce of humanity would hope for an end to the hostility on both sides."

McLaughlin has played Lucas Sinclair, the more level-headed and skeptical member of the core group, since season one, when he was 15. Now 24, McLaughlin has arguably undergone the biggest transformation — he even has a beard!

Like many of his costars, McLaughlin has continued to work with Netflix. He appeared in "High Flying Bird" (directed by Steven Soderbergh), "Concrete Cowboy," and "The Deliverance," all Netflix originals.

He had a role in the 2023 biblical comedy "The Book of Clarence," which was a box-office flop but critically well-liked. He also played former NBA player and current college coach Dru Joyce III in "Shooting Stars," a Peacock film about a young LeBron James.

"Stranger Things" isn't the only TV show he's done, either. He played Ricky Bell in the BET miniseries "The New Edition Story," and has had voice roles in "Summer Camp Island," "Ultra City Smiths," and "The Boys Presents: Diabolical."

In 2026, he will voice the lead role in the animated film "Goat."

There's also a growing movement to cast McLaughlin, who has 13 million Instagram followers, as a live-action Miles Morales.

Matarazzo, 23, plays the lovably geeky Dustin Henderson, who formed a bond with older kids Steve and Eddie. He was 14 when the show began airing.

Matarazzo has since built himself a very well-rounded career.

In addition to his movie roles ("Honor Society," "My Father's Dragon," "Please Don't Destroy: The Treasure of Foggy Mountain" and the coming "Animal Farm" remake) and theater roles ("Into the Woods," "Parade," and the original cast of the "Sweeney Todd" revival), Matarazzo has also made himself a TV personality; he executive-produced and hosted the Netflix hidden-camera series "Prank Encounters."

He also has 16.6 million followers on Instagram.

Hawke, 27, joined the show in season three in 2019, when she was 21. She plays Robin Buckley, originally Steve's coworker at Scoops Ahoy, but soon she becomes his best friend. She's also one of the show's two canonically queer characters, alongside Will.

Technically, Hawke has been famous since birth, as her parents are Ethan Hawke and Uma Thurman. But 2019 was her breakout year, as she joined "Stranger Things" and appeared in "Once Upon a Time in Hollywood."

Like the rest of her costars, Hawke has a good relationship with Netflix. She starred in "Fear Street Part One: 1994," "Do Revenge," and "Maestro," all on the streamer.

Besides that, Hawke appeared in the Wes Anderson film "Asteroid City" and the highest-grossing film of 2024, "Inside Out 2." She voiced a new emotion, Anxiety.

Next year will be a big one, though. Hawke was announced to be joining the cast of "The Hunger Games: Sunrise on the Reaping" as Wiress, originally played by Amanda Plummer in "Catching Fire." She's also costarring with Lewis Pullman in the romcom "Wishful Thinking."

Hawke has a music career, as well. She's released three albums: "Blush" (2020), "Moss" (2022), and "Chaos Angel" (2024).

She has 8.9 million followers on Instagram.

Wolfhard, 22, is the show's lead character, Mike Wheeler. He's the one who decides to go looking for Will after he goes missing and forms a special bond with the mysterious girl they meet in the woods. We know the most about his home life, as his sister Nancy is a main character, and we've met his parents and younger sister, as well.

He began playing Mike when he was 13 years old.

Wolfhard has two successful franchises to his name. He played young Richie in 2017's "It" (which made $704 million) and 2019's "It Chapter Two" (which made $473 million).

He also appeared in "Ghostbusters: Afterlife" and "Ghostbusters: Frozen Empire," which each made around $200 million worldwide.

In 2024, he had a small role in "Saturday Night," and this year, he appeared in the A24 film "The Legend of Ochi." His directorial debut, "Hell of a Summer," premiered this April and made back its budget, per The Numbers.

Wolfhard has also become a successful voice actor. He voiced Pugsley in the animated "Addams Family" movie, which also made around $200 million (though he was recast for the 2021 sequel), and voiced Candlewick in 2021's "Guillermo del Toro's Pinocchio," which went on to win best animated feature at the Academy Awards.

It's a wonder that Wolfhard also has time for a career as a musician. From 2017 to 2019, he was the lead singer of the band Calpurnia. He then joined the band The Aubreys, which released its debut album in 2021. On June 6, Wolfhard released his debut solo album, "Happy Birthday." He went on a mini-tour to support it during the month.

He has 22.2 million followers on Instagram.

At last, we've come to Keery, aka Steve "The Hair" Harrington. Steve began the show as one of the mean popular kids, but has gone through a heartwarming transformation to become a fan favorite. Also, remember that baseball bat with the nails in it? Swoon.

Keery was 24 when the show started airing, and now he's 33, the oldest of the main "kids" cast.

His career has taken off since then. He was the lead of the 2020 black comedy/horror film "Spree," starred in "Free Guy" and "Pavements," and has a future film costarring Liam Neeson, Lesley Manville, and Vanessa Redgrave called "Cold Storage."

He also had a main role in the fifth season of the anthology series "Fargo."

But where Keery's edge lies is his music. While his costars have semi-successful musical careers, Keery (as his alter ego Djo) has had real success. His song "End of Beginning" was a bona fide hit in 2024, peaking at No. 11 on the Hot 100 chart, and received Billboard Music Award and Brit Award nominations.

His 2025 album, "The Crux," peaked at No. 10 on the US Rock chart and No. 50 on the Billboard 200. It also received a Grammy nomination. The song "Charlie's Garden " is dedicated to his "Stranger Things" costar and friend Charlie Heaton.

While Keery doesn't have a personal Instagram, he does have one as Djo, which has 3.3 million followers. He was touring through October 2025.

Sink, 23, joined "Stranger Things" in season two as Max Mayfield, the new kid in Hawkins and a tomboy able to keep up with Mike and his friends, when she was 14. She eventually develops a close friendship with Eleven and begins dating Lucas in season three.

Max was one of the biggest parts of season four. A pivotal scene in which she escapes the Upside Down helped bring the 1985 Kate Bush song "Running Up That Hill" back to the top of the charts, peaking at No. 3 on the Hot 100.

Since joining "Stranger Things," Sink starred in the two Netflix horror films: "Fear Street 1978" and "Fear Street 1666." She also starred in the 2022 Oscar-winning film "The Whale," which earned her a Critics' Choice Award nomination.

She began starring in the Broadway play "John Proctor Is the Villain" in 2025, which earned her a Tony Award nomination for best actress in a play, and is set to reprise the role in its movie adaptation. She'll return to the theater — though this time in the West End — in a new production of "Romeo & Juliet" with Noah Jupe in 2026.

Sink has an undisclosed role in next year's film "Spider-Man: Brand New Day," per Deadline.

Now, we can't talk about Sink without mentioning her role as, essentially, the Taylor Swift self-insert role in "All Too Well: The Short Film," the music video for the 10-minute version of "All Too Well." If Swift picks you to play a fictional version of herself, you know you've made it.

Sink has 26.2 million followers on Instagram.

If you were on TikTok in the summer of 2022, it was impossible to miss the sound of Quinn's voice screaming for Chrissy to wake up.

Quinn, 31, joined the cast in season four as a high school (super) senior named Eddie Munson, a heavy-metal-loving, Dungeons-and-Dragons-playing sweetie who bonds with Dustin.

Quinn's this high on the list because, in the three years since he was on the show, his career has soared. Since last year, he's been in "A Quiet Place: Day One" (a hit), "Gladiator II" (another hit), "Warfare," and played the Human Torch in "The Fantastic Four: First Steps."

And that's not all. In addition to reprising his role in "Avengers: Doomsday," he was announced to be playing George Harrison in Sam Mendes' four-part Beatles movie extravaganza.

Quinn has 5.7 million followers on Instagram — not bad for someone who only joined the app in 2022 to promote "Stranger Things."

We haven't really mentioned Eleven (as played by Brown) in this ranking, because it's hard to explain her character without sounding a bit out there. But here we go: Eleven is a young girl who escaped from a secret government lab after discovering she has immense psychic powers.

Brown, 21, was easily the breakout star of the show. During Halloween 2016, that pink dress, blonde wig, fake nosebleed, and Eggo box were unavoidable.

Brown was just 12 when "Stranger Things" premiered, and received back-to-back Emmy nominations before she was 16.

Since then, she's appeared in "Godzilla: King of the Monsters" ($387 million worldwide) and "Godzilla vs. Kong" ($470 million worldwide). She's also starred and produced in four Netflix movies ("Enola Holmes," "Enola Holmes 2," "Damsel" and "The Electric State" — three of which were huge hits) and has another "Enola" film and a rom-com called "Just Picture It" costarring Gabriel LaBelle on the way.

She's proven herself to be a savvy businesswoman. She was reportedly paid $10 million for "Enola Holmes 2," and Brown has founded three successful companies: Florence by Mills Beauty, Florence by Mills Coffee, and Florence by Mills Fashion. Her beauty brand is available at Ulta, while her coffee is on shelves at Walmart.

Brown also proved just how famous she was when she married Jake Bongiovi (son of Jon Bon Jovi) in 2024, and their wedding made dozens of headlines. They've since adopted a daughter. Yes, "Stranger Things" has been on long enough for Brown to get married and become a mom.

And in case all that hasn't convinced you, Brown is far and away the most followed person from the cast, with a staggering 66.7 million followers on Instagram.

From delicious street food to incredible restaurants, the meals in Spain never disappoint.

When visiting San Sebastián, I love having the pintxos — bite-sized snacks traditionally found in the Basque Country of northern Spain. One of my favorites is gildas, small skewers of green olives, anchovies, and pickled Guindilla peppers.

Meanwhile, the best pimientos de padrón (cooked Padrón peppers) I've ever eaten were at the Mercado de San Miguel in Madrid.

And my favorite restaurant in the world, Alfarería 21 Casa Montalván, is in Seville. The food there is great, but what really makes me love it is the staff. In my experience, everyone has always been attentive and incredibly friendly.

My favorite beer, Alhambra 1925, is also Spanish, and having it is always a special treat.

One of the most-visited tourist sites in Spain is the Alhambra, a medieval palace and fortress in Granada, renowned for its complex designs and Islamic architecture.

I especially love visiting the "whispering gallery," an effect found in the Hall of the Abencerrajes. A local explained it to me during one of my many visits to the Alhambra: Essentially, the architecture allows a whisper to be heard on the other side of the room.

And just nearby is the Patio de Los Leones (Patio of the Lions), a courtyard featuring a fountain complete with 12 marble lions. I recommend booking tickets as early as possible, as they tend to sell quickly.

Other sites I recommend visiting are the Museo Reina Sofía in Madrid, which houses the famous Picasso painting "Guernica," and the Museo de la Paz de Guernica, which depicts the story of the bombing of the city during the Spanish Civil War.

Almost every town, city, and village in Spain has an annual feria (festival), and my favorite is undoubtedly La Feria del Caballo (The Horse Fair) in Jerez de la Frontera.

Held every May at the González Hontoria fairground, the festival features plenty of food, drinks, dancing, and a program of equestrian events.

It's beautiful during the day, but at night, the grounds are lit up in a spectacular way that makes everything look magical.

Another festival I enjoy attending is Las Fallas, held annually in March in Valencia. Hundreds of wooden and papier-mâché monuments called fallas are constructed around the city, and then, to conclude the festival, they're burned.

These structures often portray local and world dignitaries or critique current events, creating a blend of art, satire, and tradition that's really worth watching.

Cities like Madrid, Barcelona, Valencia, and Seville have public transportation systems that cover a lot of ground and are reasonably priced. Some single-ride bus tickets cost as little as €1.50 ($1.75).

Plus, throughout the country, I've consistently found the public transportation to be reliable, clean, and affordable.

On my last visit to Valencia, I easily took the metro and a bus to the beach, before heading to the Ciudad de las Artes y las Ciencias (City of Arts and Sciences) again by metro and bus — a door-to-door experience without a problem.

From the street art and Flamenco dancing in the Plaza de España to square trees and unique architecture, Seville has so much to offer.

But above all, what I love most about the city is its people. They're some of the friendliest folk I've ever come across. Whenever I sit in a bar or a restaurant there for half an hour, I leave with new friends.

I've lost count of the number of times I've been invited (and gone) to parties or events held by someone I met just two hours prior in Seville.

Overall, everything in this country has a charm unmatched by anywhere else I've been.

Though I've been to Spain over a dozen times, I never tire of savoring the local cuisine, taking in the beautiful views, and exploring its incredible architecture.

I'm already looking forward to returning next year to see La Sagrada Familia finally completed after more than 140 years of construction. While there, I'm sure I'll enjoy plenty of other new adventures, too.

The stateroom decks comprised long hallways lined with identical blue doors, so my magnet made it easier to find my cabin.

The cruise ship's WiFi wasn't strong enough for me to stream videos.

I enjoyed a few beach days during my cruise, so sunscreen was essential. And I was sure to pack a reef safe brand since I was visiting multiple beaches.

Aloe vera typically soothes and cools my burns, so next time, I'll pack some in case I forget to apply sunscreen.

An excursion guide at one of the ports informed me that some beaches in the Caribbean, like Tulum, Mexico, don't allow sunscreen in the ocean to protect wildlife.

As other cruisers snorkeled with phones in hand, I realized I was missing an opportunity to capture ocean life.

I don't typically wear my sun hat — especially not in my home city, New York — so the cruise was the perfect occasion to pull it out of my closet.

Mornings and evenings on the ship's top decks were so windy that I had to leave my hat in my room to avoid chasing it around.

I ended up wearing my sweater every day during the Caribbean cruise.

In hindsight, I should have packed a couple more pairs of pants. Sweatpants would have been especially useful at night on the outdoor decks.

I was often chilly at night in my sweater alone.

On my cruise, Royal Caribbean's laundry service charged for each article of clothing — $4 a shirt, $9 a dress, and $2 per pair of underwear.

I packed two pairs of shoes: sneakers for walking and waterproof sandals for the beach and pools.

A small pack was handy during port stops and while exploring the ship.

Ship time is the time zone that cruise ships adhere to even when docked at ports in different time zones.

My ship stopped in Roatan, Honduras; Costa Maya and Cozumel, Mexico; and Royal Caribbean's private island in the Bahamas, CocoCay.

I packed vitamins to support my immune system since I was coming in contact with many people.

I always pack Dramamine on my trips to avoid motion sickness.

It was especially loud since I was at the front of the ship, where seasoned cruisers said movement on ships feels the strongest.

Next time, I'll come prepared.
