Oasis of the Seas was the first of Royal Caribbean's Oasis Class, but Wonder of the Seas introduced so many improvements to these ships.
Both ships are among the largest in the world and are in the process of shifting to shorter Caribbean cruises in a move meant to attract more new cruisers.
While Oasis and Wonder are separated by over 10 years in their debuts, they're still more similar than different.
However, there are notable differences between the two worth considering before you choose one.
Ship overview
Oasis of the Seas was a gamechanger when she debuted in 2009, and it's difficult to properly convey how this one ship completely changed the cruise industry overnight.
Not only was this ship the biggest in the world, but Oasis was revolutionary for its design and how much there was to do onboard.
Oasis weighs 226,838 gross tons and can carry 5,602 passengers at double occupancy.
While that's really big, Wonder is even bigger. Wonder of the Seas was also the biggest cruise ship in the world at the time of her launch. This ship weighs 235,600 gross tons and can carry 5,734 passengers at double occupancy.
Today, Wonder is the fourth largest ship behind and Oasis is eighth.
Wonder of the Seas currently sails 3 and 4-night cruises out of Miami, visiting the Bahamas and Perfect Day at CocoCay.
Oasis of the Seas is offering 6- to 9-night Caribbean cruises from Fort Lauderdale, Florida. In 2026, Oasis moves up to Cape Liberty, New Jersey to offer cruises from the New York City area.
Here's a look at the two ship's statistics, compared:
| Ship Stats | Oasis of the Seas | Wonder of the Seas |
|---|---|---|
| Gross tons | 226,838 GRT | 235,600 GRT |
| Length | 1,187 feet | 1,188 feet |
| Width | 215 feet | 215 feet |
| Decks | 18 | 18 |
| Guest Capacity* | 5,602 | 5,734 |
*at double occupancy
Neighborhoods
Oasis of the Seas introduced the concept of neighborhoods as a way to make it easy for passengers to find their way around massive ships..
The idea is simple: distinguish areas with a common theme so that you'll instantly recognize where you are without memorizing the ship deck plans.
One key difference between Oasis and Wonder is there's an extra neighborhood on Wonder of the Seas.
- Royal Promenade: Main thoroughfare filled with bars, shops, and entertainment
- Central Park: Outdoor park with real plants and trees. You'll also find specialty dining, and shopping
- Boardwalk: Open air section on back of the ship with the Aquatheater, along with classic carousel and restaurants
- Pool and Sports Zone: Resort themed pool deck, featuring pools, waterslides (The Perfect Storm), the FlowRider surf simulator, and rock-climbing walls
- Vitality Spa and Fitness Center: A wellness-focused neighborhood offering spa treatments & fitness facilities
- Youth Zone: Adventure Ocean and teen clubs where supervised age-specific programming is offered
- Entertainment Place: A district dedicated to evening entertainment, including the ship's main theater, casino, & ice rink
- Suite Neighborhood: Only on Wonder of the Seas (and Utopia), reserved area.
Oasis has a suite sun deck, but the expanded Suite Sun Deck on Wonder is truly more impressive and feels more like a resort than simply a reserved area of the pool deck.
I think the Suite Sun Deck is so impressive on Wonder, that if you're considering booking a suite and trying to decide between ships, I'd pick Wonder for that reason.
Dining
You'll find lots of dining choices on both ships, but there are a few key differences.
Each ship has plenty of included restaurants as well as specialty dining. There's sushi, steak, a sports bar, and tropical themed pool bars.
There is room service on both ships, although it has a service fee with it (continental breakfast is free).
In comparing the ships, certain restaurants aren't available on both. You'll find Wonder has a few extra venues not available on Oasis.
It's primarily in the specialty dining where there differences. Oasis of the Seas has Portside BBQ, which is a barbecue restaurant offering turkey legs, brisket, mac 'n' cheese, pulled port and more. It's priced a la carte, although there are combo offerings.
Both ships have a Giovanni's Italian restaurant, but the version on Wonder is updated. This version has a newer menu that offers an expanded menu and updated recipes.
Another difference on Wonder is it has the Mason Jar, a restaurant serving Southern American comfort food, with live music at the popular bar area.

Staterooms
The choice in staterooms on Wonder of the Seas and Oasis of the Seas are fairly similar, with one notable suite exception.
Wonder of the Seas has 2,867 cabins, while Oasis has just 2,801 cabins. It's a small difference, made up primarily of inside rooms added in places that are public areas on Oasis.
The biggest difference is that Wonder of the Seas has the Ultimate Family Suite, and Oasis does not.
This is a two story epic suite that is designed to wow and amaze just about everyone. It includes an in-suite slide, private jacuzzi, movie room, bunk beds, giant TV, and a LEGO wall.
As you might imagine, the Ultimate Family Suite is quite expensive and often costs as much about $14,000 per night!
If you'd prefer something less expensive, you'll find plenty of other cabin choices.
Both Wonder and Oasis have balcony cabins that overlook the ocean, Central Park, or Boardwalk.
Both ships also have virtual balcony cabins, which include a floor-to-ceiling screen that projects a live view from outside the ship.
Entertainment and activities
Royal Caribbean designed both cruise ships to offer as much as possible onboard, and they won't leave you disappointed with there not being enough to do.
There are shows in three different theaters, live music, pools, casino gambling, surfing, laser tag, and rock climbing abound on both vessels.
One key difference is Oasis of the Seas has a full Broadway show onboard, whereas Wonder relies on shows produced by the cruise line.
"Cats" is performed on each sailing of Oasis of the Seas, and it's included in your cruise fare.
Both ships have amazing performances in the Aquadome, where there are high dive acrobat shows.
I prefer the Aqua80s show on Oasis of the Seas because of the tribute to the music of the 80s!
It's also worth noting Wonder of the Seas has the Vue Bar, whereas Oasis does not.
As its name implies, the Vue Bar offers sweeping ocean views from the pool deck.
Each night you'll find bars and lounges that feature live music. The two ships, however, do vary in entertainment venues.
| Bars & Lounges | Wonder of the Seas | Oasis of the Seas |
|---|---|---|
| Lime and Coconut | ✓ | ✓ |
| Bionic Bar | ✓ | ✓ |

One difference (for now) is that Oasis of the Seas is sailing weeklong voyages, whereas Wonder of the Seas has transitioned to weekend cruises.
Royal Caribbean wants Wonder to have more of a party vibe to it, making it appealing to new cruisers who want to try it out.
Wonder is nicknamed, "Miami’s New Weekend Wonder" and has 10 next-level parties.
This includes:
- Bring the Beat Back: A Party Through the Decades
- Sailaway Party
- Plunge Day Pool Party
- Royal Kappa Chi (college party)
- Silent Toga Party
Oasis of the Seas isn't a floating library by any means. You'll find lots of parties and events happening. Both ships have themed nights and dance, DJ, and street parties.
