The 6,699-passenger Oasis of the Seas was the largest vessel at sea when it launched in 2009. It has since been eclipsed by two other Royal Caribbean ships (Harmony of the Seas and Symphony of the Seas), but this vessel is still a mammoth sight to behold. There are seven "neighborhoods" throughout Oasis, including a bustling Boardwalk with a classic carousel and a Central Park filled with over 12,000 plants and upscale boutiques that are designed to mirror New York City’s famous Fifth Avenue.
On its 10th anniversary in 2019, Oasis of the Seas underwent a $165 million refurbishment. Enhancements include the addition of 59 staterooms (including two luxury Ultimate Panoramic Suites), an updated adults-only area (The Solarium), plus new restaurants, bars, entertainment venues, and more. Oasis currently sails from Miami to the Caribbean (the vessel also visits Labadee, the cruise line’s private island in Haiti); however, in May 2020, the ship will reposition to Cape Liberty, NJ to cruise Florida and the Bahamas (including Royal Caribbean’s CocoCay island).
