Harmony of the Seas mega-ship is on course to be world’s largest

You could spend your whole day going up and down three waterslides that spiral down 10 decks on the upcoming Harmony of the Seas cruise ship from Royal Caribbean International.

The cruise line on Wednesday announced features of the ship that’s scheduled to make its debut in April 2016. It will be the world’s largest cruise ship and the third in the line’s Oasis class, according to news reports.

Harmony of the Seas will feature 2,747 staterooms and hold 5,479 passengers on 16 decks, surpassing its sister ships Oasis of the Seas and Allure of the Seas, Royal Caribbean’s announcement says.

Like other ships in this class, it will feature seven “neighborhoods,” or activity zones: Central Park, Boardwalk, the Royal Promenade, the Pool and Sports Zone, Vitality at Sea Spa and Fitness Center, Entertainment Place, and the Youth Zone.

You can play on a carousel and in a games arcade on the Boardwalk, take water slides that swirl from the top down to Central Park, and grab a drink from the robot bartenders (which debuted on Quantum of the Seas) at the Bionic Bar on the Royal Promenade.

Fast Internet and high-tech wristbands that open stateroom doors and charge expenses will be available on board too. Dining options include specialty restaurants Izumi Hibachi & Sushi for Japanese food and Sabor Modern Mexican.

Royal Caribbean has three ships coming on line in the next 18 months: Anthem of the Seas, a Quantum-class ship that will debut this April in Southampton, England; and Ovation of the Seas and Harmony of the Seas, both scheduled for April 2016.
