Royal Caribbean has the three largest cruise ships ever built. The fleet has 30 ships across seven classes, and each class offers a different experience. Surprisingly, the ship you choose can affect your vacation even more than the destinations you visit!
Imagine a family books a Royal Caribbean cruise, looking forward to water slides and a zip line. When they board, they find a charming older ship with a beautiful theater and a quiet pool deck, but no water park. The trip is still enjoyable, but it’s not what the kids expected.
I’ve seen this kind of mix-up happen often. Let’s clear things up. I’ll guide you through each ship class, explain what they’re really like, highlight what’s coming in 2026, and share the small details that can make a big difference on your trip.
Royal Caribbean Ships at a Glance
Here’s a quick overview:
- Fleet size: 30 ships
- There are seven classes: Icon, Oasis, Quantum (including Quantum Ultra), Freedom, Voyager, Radiance, and Vision.
- The newest ship is Legend of the Seas, which had its maiden voyage on July 4, 2026.
- The biggest ships are Icon, Star, and Legend of the Seas.
- The oldest and smallest ship is Grandeur of the Seas, launched in 1996.
- Coming next: Hero of the Seas in August 2027, then a new Oasis Class ship in 2028
Royal Caribbean Ship Classes, From Biggest to Smallest
A class is like a family of sister ships that share a similar layout and most major features. Once you know the classes, the whole fleet is easier to understand.
Icon Class: The Record Breakers
- Ships: Icon of the Seas (2024), Star of the Seas (2025), Legend of the Seas (2026)
- Size: About 250,000 gross tons and 1,196 feet long
- Guests: 5,610 at double occupancy, up to 7,600 when every bed is full
- Home ports: Icon sails from Miami, Star from Port Canaveral, and Legend from Fort Lauderdale
When you step onto the top deck, you’ll probably hear kids laughing and sliding down Category 6, the largest water park at sea. Parents can relax at the swim-up bar, while little ones have their own area called Surfside. Above, the glass AquaDome features an indoor AquaTheater.
If your kids are between 6 and 16, start here. The trade-off is price. On sea days it can also feel like a theme park in July.
Oasis Class: Resort Living at Sea
- Ships: Oasis (2009), Allure (2010), Harmony (2016), Symphony (2018), Wonder (2022), Utopia (2024)
- Size: About 225,000 to 236,000 gross tons
Oasis Class introduced the idea of “neighborhoods” on board. Central Park is an actual open-air garden in the middle of the ship. The Boardwalk features a carousel and the AquaTheater, where high divers perform while the ship’s wake churns behind them.
Insider tip: Don’t skip Allure because of old blog posts calling her outdated. Her 2025 refit, which cost over $100 million, added the Ultimate Abyss dry slide, the Perfect Storm water slides, and the Pesky Parrot tiki bar!
Quantum and Quantum Ultra Class: Fun in Any Weather
- Ships: Quantum (2014), Anthem (2015), Ovation (2016), Spectrum (2019), Odyssey (2021)
- Size: About 168,000 gross tons
These ships bring the fun inside. At SeaPlex, you’ll find bumper cars and sports courts. RipCord by iFLY lets you try indoor skydiving, and the North Star glass capsule takes you over 300 feet above the ocean.
If you’re heading to Alaska, I’d start by looking at a Quantum ship. There’s nothing like relaxing by a warm indoor pool while watching ice float by outside.
Freedom Class: The Sweet Spot
- Ships: Freedom (2006), Liberty (2007), Independence (2008)
- Size: About 155,000 gross tons
Freedom of the Seas was the first to offer the FlowRider surf simulator at sea. You’ll also find an ice rink, the Royal Promenade, and that big-ship feel—without having to walk long distances.
Voyager Class: Where the Promenade Began
- Ships: Voyager (1999), Explorer (2000), Adventure (2001), Navigator (2002), Mariner (2003)
- Size: About 138,000 gross tons
Voyager of the Seas was the first to feature the Royal Promenade, an indoor main street with cafes and parades. Upgrades can differ a lot between ships in this class, so check your specific ship. For example, Navigator got a big update in 2019.
Radiance Class: Glass and Glaciers
- Ships: Radiance (2001), Brilliance (2002), Serenade (2003), Jewel (2004)
- Size: About 90,000 gross tons
There’s floor-to-ceiling glass throughout the ship. Imagine sipping your morning coffee as mountains pass by. These smaller ships can also visit ports that the larger ones can’t reach.
Vision Class: Small and Charming
- Ships: Grandeur (1996), Rhapsody (1997), Enchantment (1997), Vision (1998)
- Size: About 74,000 to 83,000 gross tons
It only takes a few minutes to walk from your cabin to the pool, and the bartenders quickly remember your name! These ships are perfect for trips with lots of port stops, but they’re not the best choice for teens looking for things like laser tag.
What’s New and Coming for Royal Caribbean Ships
Legend of the Seas Arrives in Florida
Legend spent the summer of 2026 in the Mediterranean as the first Icon Class ship to sail in Europe. It will arrive at Port Everglades on November 7. The first Fort Lauderdale sailing is a three-night trip to the Bahamas on November 8, 2026. This ship uses liquefied natural gas (LNG), which is a cleaner-burning fuel.
Hero of the Seas (2027)
The fourth Icon Class ship will sail from Miami in August 2027. It is expected to feature nine pools, family raft slides, and a three-story Ultimate Family Treehouse.
Discovery Class (2029 and 2032)
This is the next big change. Royal Caribbean ordered two Discovery Class ships in January 2026. They’re the first new class in years that isn’t focused on size. Early details show about 4,300 guests per ship, with plans to sail in Asia, Alaska, and Europe.
What’s Included, and What Isn’t
Included in your fare:
- Your cabin, with daily housekeeping
- The Main Dining Room, the Windjammer buffet, and casual spots
- Water, tea, basic coffee, and some juices
- Pools, shows, the fitness center, and the Adventure Ocean kids’ club
- Many thrills, like rock climbing, mini golf, and waterslides on ships that have them
Costs extra:
- Alcohol and specialty drinks
- Specialty restaurants
- Wi-Fi
- Shore excursions
- Spa visits, the casino, and the arcade
Tips (gratuities): Royal Caribbean adds $18.50 per person per day, or $21 per person per day for suites. An 18% charge is added to Royal Caribbean drinks, specialty dining, and room service, while spa services have a 20% charge. You can prepay daily tips before your cruise or adjust them at Guest Relations on board.
Hidden Details Most Guides Miss
- The diaper rule: Kids in diapers can only use Baby Splash areas, not regular pools. Radiance and Vision ships don’t have these areas, and Adventure is the only Voyager ship that does. This is more important than the number of slides on a ship.
- Smart elevators: On Icon Class ships and Utopia, you select your deck on a screen outside the elevator. The system assigns you a lettered elevator, and there are no buttons inside.
- Accessible cabins: These cabins have doors that are 32 inches wide, compared to at least 23 inches for standard doors. Be sure to submit the Special Needs form at least 30 days before your cruise.
- Beach clubs: Royal Beach Club Paradise Island opened in December 2025. The Santorini club opened in summer 2026, and the Cozumel club is expected at the end of 2026.
- Book early: AAA predicts that over 22 million Americans will cruise in 2027, so popular weeks can sell out quickly.
How to Pick the Right Royal Caribbean Ship
1. Choose your destination and travel dates first, since not every ship class sails in every region.
2. List your top three must-haves, like a teen club, a balcony, or a port you can drive to.
3. Check the exact ship. Sister ships can differ after their upgrades.
4. Consider how many sea days you’ll have. If your trip has lots of port stops, onboard extras may matter less.
5. Look at the total trip cost, including flights, hotels, tips, and excursions—not just the cruise fare.
Quick matches:
- Big family thrills: Icon or Oasis Class
- Alaska: Quantum or Radiance Class
- Value with fun: Freedom or Voyager Class
- Quiet and port-focused: Radiance or Vision Class
