Harmony of the Seas
Harmony of the Seas launched in May 2016, at the time as the largest cruise ship in the world at 227,700 GT. The ship’s latest technology includes high speed internet (as if you are at home), an onboard mobile device app to track luggage and make reservations, and RFID WOWBands (alternatives to SeaPass cards). Other features are a 10-story Ultimate Abyss water slide, surfing on the Flowrider, and rock climbing.
