Introducing to you the Harmony of The Seas. For those that don't know what this is, it's the newest addition to Royal Caribbean's award-winning Oasis Class fleet. The world's biggest ship with the world's best features just got even better.

According to USA Today the Harmony of The Seas is one of the most-anticipated new vessels in years. It will eclipse its siblings by more than 1,700 tons and hold nearly 100 more passengers at double occupancy. Its total capacity will be well over 6,000 people and 2,000 crew members.

Harmony of The Seas has been under construction at the STX shipyard in St. Nazaire, France for more than a year, and the sea trials are taking place off the coast of France.

Designed for vacationers who love big, bustling mega-resorts, Harmony will feature a giant, multi-deck water slide area a first for Royal Caribbean. Harmony also will be the first Oasis class ship with a Bionic Bar where the drinks are served by robot bartenders.

The Harmony of the Seas has 18 decks and stretches 1,187 feet. A key attraction on board is The Ultimate Abyss which spreads across 10 decks at more than 150 feet above the waves.

There’s also a zip wire, merry-go-round, deck games, hot dog stand, diner and Mexican restaurant. For the risk takers, there’s the Perfect Storm trio of water slides, which intertwine with the 40 tall trees and 12,000 other plants of Central Park. There’s also an indoor ice skating rink, two rock-climbing walls, theatres, water parks and fitness facilities.
