Not all Royal Caribbean ships are created equal.
In fact, the ship class you choose can completely change your cruise experience.
Whether you’re dreaming of surf simulators and skydiving simulators, or you’d rather sip wine in peace with a view of the fjords, knowing the difference between Royal Caribbean ship classes is the key to cruising smarter.
Royal Caribbean currently has seven ship classes sailing the seas. Some are massive floating cities with more thrills than a theme park. Others are smaller, quieter, and able to visit ports that big ships can’t even dream of docking at.
And while ships within each class share a similar structure, there are always surprising differences in dining, entertainment, layout, and vibe.
In this ultimate guide, I’ll break down:
- What makes each Royal Caribbean ship class unique
- Which class is best for you (families, budget cruisers, solo travelers, etc.)
- My honest take on which ones are worth the hype
So if you’re wondering, “Should I book Icon of the Seas or something smaller?” — you’re in the right place.
Let’s go.

What Are Royal Caribbean Ship Classes?
If you’ve ever wondered why some ships have waterslides and zip lines while others feel more like a classic cruise throwback, the answer usually comes down to ship class.
Royal Caribbean ship classes group ships by their size, layout, and overall design. Think of each class like a blueprint. Ships built within the same class are based on the same overall structure, with similar amenities, neighborhoods, and features. But just like siblings, no two ships are exactly alike.
Royal Caribbean has introduced seven distinct ship classes over the years:
- Icon Class (the newest and biggest)
- Oasis Class (floating resorts)
- Quantum Class (tech-forward and modern)
- Freedom Class (big but budget-friendly)
- Voyager Class (the OGs of innovation)
- Radiance Class (sleek, scenic midsize ships)
- Vision Class (smallest, with unique itineraries)
Want to make sure the places you’re cruising to are actually worth the stop? After you’ve picked your ship, check out the 7 best Royal Caribbean Caribbean ports that are 100% worth visiting to see which destinations are truly unforgettable.
Each time a new class launches, it usually brings first-time features to the fleet, like new neighborhoods, cutting-edge tech, or headline-worthy attractions. Over time, Royal Caribbean does retrofit older ships with some of these upgrades, but they never completely match the newer ships in size, layout, or design.
So what’s the real difference between Royal Caribbean ship classes?
It comes down to more than just size. Each class has its own:
- Vibe (family fun vs. quiet relaxation)
- Entertainment options (skydiving? Broadway shows?)
- Dining style (grab-and-go vs. fine dining variety)
- Ship layout (easy-to-navigate or mega-resort feel)
- Itineraries (some visit places the bigger ships can’t even dock)
If you’re looking to cruise with specific amenities like a swim-up bar, Central Park, or bumper cars, it’s crucial to know which ship class offers what before you book.
That’s exactly why this guide exists — to help you understand the difference between Royal Caribbean ship classes and choose the right one for your cruise style.
Icon Class
Among all Royal Caribbean ship classes, the Icon Class stands out as the newest and boldest, led by the record-breaking Icon of the Seas. This is the class that officially redefined what a cruise ship can be.
With over 250,000 gross tons and the capacity for up to 10,000 people onboard (guests + crew), these ships are the largest cruise ships in the world. If you’re comparing Royal Caribbean ship classes by size, this one easily takes the crown. But don’t let the size scare you. Thanks to smart layout and neighborhood design, Icon Class ships actually feel surprisingly open and manageable.
What makes Icon Class different?
Unlike any other class before it, Icon Class ships are designed with eight distinct neighborhoods, each with its own personality:
- AquaDome – an indoor space with a massive waterfall and AquaTheater shows
- Chill Island – Royal Caribbean’s largest pool deck
- Thrill Island – home to Category 6, the biggest waterpark at sea
- Surfside – a family-focused zone with splash areas, mini eateries, and a dedicated pool
- Central Park – a serene garden space with walkable paths and open-air dining
- The Hideaway – adult vibes only, with a suspended infinity pool
- Suite Neighborhood – an exclusive area for suite guests only
- Royal Promenade – shops, bars, entertainment, and the iconic Pearl
You’ll also find:
- The first-ever swim-up bar at sea
- AquaTheater shows with a retractable dome
- The Pearl, a stunning 36-foot sphere that lights up and pulses with sound
Icon of the Seas is also Royal Caribbean’s first LNG-powered ship, making it more fuel-efficient and sustainable than older ships in the fleet.
Icon Class Ships
- Icon of the Seas (2024)
- Star of the Seas (2025)
- Legend of the Seas (coming 2026)
- Fourth Icon Class ship (2027, name TBA)
Royal Caribbean has also hinted at a fifth and sixth Icon Class ship, but those haven’t been confirmed yet.
Icon Class Highlights
- Thrill Island waterpark with the tallest waterslide at sea
- The Hideaway: first suspended infinity pool at sea
- Cloud 17: adults-only retreat

Why Choose Icon Class?
If you’re cruising with kids, teens, or multi-gen groups, Icon Class is pure magic. It’s also perfect for first-timers who want that “wow” experience right out of the gate. Yes, it’s big, but it’s also beautiful, high-tech, and surprisingly efficient.
This isn’t just a cruise. It’s a floating theme park, waterpark, foodie tour, and beach resort all in one. Among all Royal Caribbean ship classes, this one is the ultimate crowd-pleaser.
Oasis Class
Before Icon Class took the crown, the Oasis Class ships were the undisputed giants of the sea. And even now, they’re still some of the most impressive cruise ships ever built.
Launched in 2009 with Oasis of the Seas, this class introduced the groundbreaking idea of ship “neighborhoods,” split decks, and a jaw-dropping amount of space to explore. These ships are enormous, but don’t let that intimidate you — they’re surprisingly easy to navigate thanks to smart design and tons of hidden nooks. Among all Royal Caribbean ship classes, Oasis Class remains one of the most innovative and beloved.
What makes Oasis Class ships unique?
All Oasis Class ships are loaded with over-the-top features, including:

They also pioneered the concept of Loft Suites, multi-level rooms with sweeping views — and often come with Royal Genie service if you book Star Class.
Many Oasis Class ships have gone through Royal Amplified upgrades, adding waterslides, laser tag, new dining venues, and tech improvements.

Think of Oasis Class as the cruise line’s greatest hits — a fan-favorite within the lineup of Royal Caribbean ship classes that continues to wow, year after year.
Quantum Class
If Oasis Class is about jaw-dropping size and neighborhood design, the Quantum Class is all about high-tech features, futuristic style, and indoor versatility.
These ships were built with cooler weather itineraries in mind (Alaska, Asia, Northeast), so you’ll find more indoor venues, observation lounges, and interactive activities that work rain or shine.
Quantum Class ships are also home to some of the most unique attractions at sea, like skydiving simulators and the glass-enclosed North Star viewing capsule. Among all Royal Caribbean ship classes, this one is the go-to for high-tech adventure.

- Anthem of the Seas
- Ovation of the Seas
- Spectrum of the Seas (Quantum Ultra)

Today, Voyager Class ships still sail strong. Thanks to upgrades and amplifications, they remain a solid and affordable option for cruisers who want a fun ship without the overwhelming size or price tag of newer classes.

If you’re dreaming of ocean views, peaceful vibes, and scenic cruising, the Radiance Class might be exactly what you’re looking for.
These ships were built with glass everywhere — elevators, lounges, dining rooms — so you always feel connected to the sea. They’re also smaller and more maneuverable, which means they can access ports the bigger ships can’t even approach.
Perfect for destinations like Alaska, Hawaii, and Northern Europe, Radiance Class ships offer a more relaxed, classic cruise experience — without feeling outdated.
Among the Royal Caribbean ship classes, this one is all about connection to the sea and port-rich itineraries.
