MS Oasis of the Seas is an Oasis-class cruise ship, delivered to her owner, Royal Caribbean International, in October 2009. The first of her class, she was joined by her sister ship MS Allure of the Seas in December 2010. Both vessels cruise the Caribbean from Port Everglades in Fort Lauderdale, Florida. She set a new record of carrying over 6,000 passengers. The ship surpassed the Freedom-class cruise ships (also owned by Royal Caribbean) to become the largest cruise ship in the world at that time. She has, however, since been surpassed by Allure of the Seas, which is 50 millimetres (2.0 in) longer, although this difference may have been caused by different temperatures when the measurements were made.
Oasis of the Seas offers passengers features such as two-story loft suites and luxury suites measuring 1,600 sq ft (150 m²) with balconies overlooking the sea or promenades. The ship features a zip-line, a casino, a miniature golf course, multiple night clubs, several bars and lounges, a karaoke club, comedy club, five swimming pools, volleyball and basketball courts, theme parks and nurseries for children. Many of the ship’s interiors were extensively decorated by muralist Clarissa Parish. Onboard recreational, athletic, and entertainment activities are organized into seven themed areas called “neighborhoods”, a concept which bears resemblance to theme park planning.
Central Park features boutiques, restaurants and bars, including access to the Rising Tide bar, which can be raised or lowered between three decks. It has the first living park at sea with over 12,000 plants and 56 trees.
The Pool and Sports Zone features a sloped-entry beach pool and two surf simulators.
Vitality at Sea Spa and Fitness Center features a spa for teens. The gym has 158 cardio and resistance machines, classes, and a range of spa services.
Boardwalk features a handcrafted carousel, restaurants, bars, shops, two rock-climbing walls, and a temporary tattoo parlor. Its outdoor 750-seat AquaTheatre amphitheater hosts the ship’s largest freshwater pool.
Royal Promenade features restaurants and shops and is viewable from a mezzanine.
Youth Zone features a science lab and computer gaming.
