Editorial Cruise Ship Wiki's take on Oasis of the Seas
Oasis of the Seas entered service in 2009 as the first ship of Royal Caribbean's Oasis class, and one decision explains her. Her superstructure was split down the middle for much of its length, opening a canyon through the ship where a solid block of cabins would otherwise sit. That gap became Central Park, a genuine open-air garden at sea, and it made the neighbourhood concept possible: distinct zones rather than one continuous vessel. Nothing afloat was built that way before her. Every large ship since borrows from her drawing. She carries roughly 5,600 guests at double occupancy across some 2,700 cabins and about 226,000 gross tons. An amplification in 2019 added waterslides, restaurants and a rebuilt pool deck. She sails Caribbean and Bahamas itineraries, splitting her year between Cape Liberty in New Jersey and Florida.
The neighbourhoods still work. Central Park is quiet and green in a way that photographs badly and works in person, with 150 Central Park and Chops Grille off its paths. The Boardwalk keeps its carousel and its seaside-pier logic, with Playmakers at the rail. The AquaTheater remains one of the better ideas in cruising. Portside BBQ and El Loco Fresh handle casual eating, Izumi and Giovanni's Table the paid end. The Ultimate Abyss, the Perfect Storm slides and the FlowRiders give the top decks real purpose, and the Solarium is unusually generous.
The criticism is fair and mostly about age. Royal Caribbean Blog's 2025 review called the cabins the weakest part of the ship: original 2009 fittings, few power outlets, no USB sockets and thin storage. The Windjammer is small for the headcount and congests at breakfast. The entertainment has not changed much in over a decade. She lacks the Suite Neighborhood built into Wonder and Utopia. Royal Caribbean Blog ranked her fourth of six Oasis-class ships in 2024, preferring the updated layouts of the newer sisters. U.S. News gives her an expert rating of 4.0 out of 5.
She suits families, first-time cruisers and anyone who wants the Oasis experience without the newest-ship premium, and her fares generally undercut Wonder and Utopia. She does not suit anyone who wants current hardware, a serious suite product, or a small quiet ship.
This matters most when choosing a cabin. Oasis introduced the interior-facing balcony, and both types remain the interesting choice here. Central Park balconies are sheltered and calm by day, though the ones low and forward catch live music and restaurant noise into the evening. Boardwalk balconies look down the length of the Boardwalk towards the AquaTheater. That buys a free seat for the diving show and also the rehearsals, the announcements and the carousel. Cabins under the pool deck hear chairs from early. Because she was first of the class, some cabin layouts and deck geometry differ from later sisters, so plans drawn from Symphony or Wonder do not transfer cleanly. We are still mapping her venues.

Oasis of the Seas was Royal Caribbean International's audacious answer to the question of how large a cruise ship could reasonably become, the lead vessel of the Oasis class and, on her 2009 debut, the largest passenger ship ever built. Ordered under the working name 'Project Genesis,' she was constructed at the STX Europe Turku Shipyard in Finland at a cost of roughly US$1.4 billion, her keel laid in November 2007 and the completed hull delivered in the autumn of 2009. At some 225,000 gross tons, about 360 metres long and spread across sixteen guest decks, she could carry more than 5,400 passengers at double occupancy and over 6,700 at maximum, dwarfing every ship then afloat.
Her central innovation was the division of the vessel into seven distinct 'neighborhoods,' a concept that reorganized the megaship around themed districts rather than a single soaring atrium. The open-air Central Park, planted with thousands of live tropical plants down a canyon carved through the middle of the ship, and the Boardwalk, a seaside-carnival zone anchored by a hand-carved carousel and a rock-climbing wall, were made possible by a distinctive split-superstructure design. The ship also introduced the AquaTheater, an outdoor amphitheater with a diving pool at the stern, alongside a full-size ice-skating rink, a zip-line strung nine decks above the Boardwalk, twin FlowRider surf simulators, and later the Ultimate Abyss, a ten-story dry slide.
Oasis of the Seas was christened in an unusual ceremony that named seven godmothers, among them Gloria Estefan, Michelle Kwan, and Jane Seymour, each honored for achievement in a different field. Her maiden voyage sailed from Fort Lauderdale in December 2009, and to reach her Florida home she famously had to lower her telescoping funnels to clear the Great Belt Bridge in Denmark.
Over the following years the ship underwent major refurbishments that added new dining venues, waterslides, and the Ultimate Abyss, keeping her competitive with her ever-larger sisters. Registered in Nassau, Bahamas, and homeported at Port Everglades in Fort Lauderdale, Oasis of the Seas continues to sail Caribbean itineraries, the founding member of a class that reshaped the entire industry and remains in active service.
Getting around - smart elevators: Royal Caribbean has been rolling out destination-dispatch "smart elevators" across its largest ships, including the Oasis class. Where fitted, guests select their deck at a console outside the elevators and are directed to a specific lettered car (A, B, C, and so on) rather than pressing a button inside the car; the system groups riders by destination to reduce waiting time.
