Harmony of the Seas, June 2016

The biggest cruise ship in the world, at 227,000 gross tons, can accommodate 5,497 passengers at double occupancy (and a whopping 6,410 when sailing at maximum occupancy). Harmony of the Seas is part of Royal Caribbean’s Oasis Class, which includes uber-popular megaships Oasis of the Seas and Allure of the Seas. The new cruise ship includes a lot of favorites from its sisters, such as a seven-“neighborhood” concept that creates themed areas like “Entertainment Place” and the “Pool and Sports Zone.” But Harmony of the Seas delivers plenty of its own excitement, including a new-to-fleet water slide area, with three slides collectively called “The Perfect Storm,” as well as a 10-story spiral slide called “The Abyss.” The new Royal Caribbean cruise ship will be completely high-tech, with the line’s VOOM, a high-speed Internet service Royal Caribbean says allows passengers to surf, share and even stream at speeds equal to those on land — still a relative rarity at sea. It offers wristbands that can be used as your cabin key and to pay for onboard purchases, and it features robot bartenders. Deployment: Mediterranean, Caribbean,www.cruiseadvisor.club
