I tried every Oasis Class cruise ship, here's how I would rank them
In:In the past four years, I’ve cruised on all six of Royal Caribbean’s Oasis Class cruise ships, and I’m ranking them from best to worst.

Oasis Class ships have turned heads ever since the first ship, Oasis of the Seas, launched in 2008. She was anything but a traditional cruise ship. For the first time ever, a Royal Caribbean ship was split into distinct neighborhoods.
Whether the family-friendly, open-air Boardwalk at the ship’s aft or two-story Royal Promenade, the Oasis Class truly redefined what a cruise ship could be.
Throughout the past sixteen years, five more Oasis Class ships have launched: Allure of the Seas, Harmony of the Seas, Symphony of the Seas, Wonder of the Seas, and Utopia of the Seas. After cruising on every Oasis Class ship, I’ve come to favor some more than others.

All six Oasis Class vessels are more alike than different, but each ship offers varied entertainment, restaurants, and onboard activities. Other touches, such as decor or differences in layout, change from ship to ship, too. Don’t get me wrong—all of my cruise experiences were excellent—but in the end, the most subtle of differences made me favor one over the other.
Here’s my ranking of Royal Caribbean’s Oasis Class ships from best to worst.
Allure of the Seas

Following her $100M amplification, Allure of the Seas has earned the top spot on my list.
In April 2025, the vessel completed a major renovation which added new venues, activities, and entertainment to the ship. After spending four nights onboard, I was impressed by the new features and amenities.
I loved the addition of The Mason Jar, Royal Caribbean's southern-inspired bar and restaurant. The venue is also available on Wonder of the Seas and Utopia of the Seas, but I preferred the spacious layout on Allure.

Other venues, like Playmakers Sports Bar and Arcade, the Pesky Parrot tiki bar, and The Lime and Coconut, were also added during her amplification.
There's a range of new activities to try, too, including the Ultimate Abyss dry slide, Splashaway Bay, laser tag, and waterslides.
If all that isn't enough, Allure's entertainment is among the best in Royal Caribbean's entire fleet. The Broadway production of Mama Mia! in the Royal Theater is exceptional, and the all-new Aqua80Too show features mind-blowing acrobatics and high-diving in the ship's AquaTheater.

Although Allure of the Seas is over a decade older than the newer Oasis Class ships, her recent amplification puts her on an even playing field with others in the class.
I thought Allure offered a great value, and her European and Caribbean itineraries are far more interesting than those found on other Oasis Class ships. I'd definitely book another cruise on the vessel.
Wonder of the Seas

The second ship on my list is Wonder of the Seas, which launched in early 2022. The ship’s layout, design features, and restaurants make Wonder one of my favorites in her class.
Wonder of the Seas was the first Oasis Class ship to have a slightly different layout from her sister ships. A Suite Neighborhood was added to the upper decks, the Windjammer buffet was expanded to decrease crowding, and the adults-only Solarium became fully enclosed for better climate control.

Everything on Wonder of the Seas felt exceptionally modern and well-designed during my week onboard. I loved listening to live country music at The Mason Jar, grabbing a drink from the tropical Lime and Coconut bar on the pool deck, and relaxing in the Solarium without breaking a sweat.
The ship is nearly identical to Royal Caribbean’s brand-new Utopia of the Seas, but it's slightly cheaper, placing it higher on my list.

Of course, not everything on the ship is perfect. I wish Wonder of the Seas featured a Broadway musical, for instance, but in general, I found the cons minimal. If given the chance to sail on an Oasis Class ship today, a cruise on Wonder of the Seas would be one of my top choices.
Utopia of the Seas

Royal Caribbean’s newest Oasis Class ship, Utopia of the Seas, aims to provide the “Biggest Weekend” at sea. The ship, which only sails 3 and 4-night itineraries, markets toward cruisers in search of a quick getaway filled with themed parties and nonstop entertainment.

From the all-new Royal Kappa Chi college-themed party to the Toga Silent Disco, the three days I spent on Utopia of the Seas were anything but boring. And even though I wouldn’t say the party vibe was entirely my vibe, participating in such activities was not a requirement.

On the whole, the ship’s atmosphere did not feel drastically different to that of other Oasis Class ships. If you didn’t attend the evening parties, sailing on the ship mostly felt like cruising on any other ship in the class.
The layout and amenities were nearly identical to Wonder of the Seas, with a Suite Neighborhood and colorful pool deck. I appreciated the addition of a few venues not found on any other Oasis Class ship, including the Royal Railway immersive train car restaurant.

Newer is usually better when it comes to cruise ships, but the sticker price of the shiny new vessel is steep. I can’t justify paying the same price for a 3-night cruise that I could pay for a 7-night cruise on a slightly older Oasis Class ship.
There’s no question that sailing on Utopia of the Seas is fun and that she provides the best-of-the-best Oasis Class features, but I’d still rather book a longer cruise itinerary.
Oasis of the Seas

Among my favorite Oasis Class ships is Oasis of the Seas. Of all of Royal Caribbean's ships, the first Oasis Class ship was perhaps the most influential. While we might now view a park on a cruise ship with normalcy, this certainly wasn’t the case in 2008!
Over the years, as expected, Oasis of the Seas began to show her age. In 2019, she underwent a $165 million amplification, which added waterslides, new restaurants, and a reimagined pool deck.

I sailed on Oasis of the Seas after her amplification, and I loved every minute of my experience onboard. I tried out the escape room, rode the Ultimate Abyss dry slide, and sipped on fruity cocktails on the Caribbean-inspired pool deck.
During my cruise, I particularly enjoyed the spacious outdoor sun deck in the Solarium along with Aqua80, the ship’s high-energy AquaTheater show. I also splurged on a pass to the spa’s thermal suite, which surely helped me enjoy my cruise even more.

In short, I didn’t find much at all to complain about on Oasis of the Seas. I prefer the more updated layout of Wonder and Utopia of the Seas, but the amplification of Oasis of the Seas helped the ship feel just as contemporary as newer ships in the class.
Symphony of the Seas

Next on my ranking is Symphony of the Seas, the fourth Oasis Class ship that launched in 2018. After spending a week onboard the ship, I found no major issues with the vessel, and my Western Caribbean vacation was just about perfect.

All things considered, Symphony of the Seas could easily be in my top three favorite Oasis Class ships. I found the ship impeccably clean, and I appreciated the design features throughout, especially the Solarium's Big Wonder art installation that lights up at night.

Additionally, my favorite Italian restaurant on Royal Caribbean, Jamie’s Italian, is found onboard, and I loved watching the ship’s Broadway production of Hairspray.
So why the lower ranking? Ultimately, I prefer the enhanced layout and offerings of Wonder and Utopia, along with the Caribbean pool vibe you can also find on Oasis and Allure of the Seas.
I wouldn’t purposely avoid Symphony of the Seas over the four aforementioned ships, but given the chance, it would probably be my fifth choice for an Oasis Class cruise vacation.
Harmony of the Seas

As if the Oasis Class ships couldn’t be game-changing enough, the launch of Harmony of the Seas in 2016 brought an even bigger wow factor to the Oasis Class.
Compared to the two Oasis Class ships built before her—Oasis and Allure—Harmony of the Seas debuted with upgraded activities. She had the first-ever waterslides on an Oasis Class ship along with the Ultimate Abyss dry slide and an escape room.

In a way, Harmony paved the way for the next three Oasis Class ships, which all share these features, and also inspired the amenities added during Oasis of the Seas’ and Allure of the Seas' amplifications.

Despite being a cutting-edge ship at the time, Harmony of the Seas ranks last on my list. Truthfully, though, she is so similar to Symphony of the Seas that I had to nitpick in order to rank her lower on the list.
Simply put, I prefer Hairspray over Harmony’s Broadway production of Grease, and I would prefer if the ship had a pool in the Solarium as opposed to just jacuzzis.
Obviously, none of these differences are deal breakers. I would never hesitate to sail on the ship again, but I would probably pick the other ships first.
