World's largest cruise ship is so vast that guests will have to use GPS to find their room
(4)

Mechanical service: Among the unique features on the Harmony Of The Seas, is a bionic bar where robots will pour passengers cocktails

Size: Harmony Of The Seas is 330ft longer than the Titanic and is as high as seven double decker buses stacked on top of each other

Engine room: Three power pods, each with 20ft propellers, along with four bow thrusters for manoeuvring, power the ship forward

The ship has 16 restaurants and cafes – including a Jamie’s Italian – boutique shopping on the Royal Promenade, and high-speed wi-fi in the staterooms. And for voyagers wanting a challenge, there’s the Escape Room where guests have to try to break out by solving a series of puzzles.

Vast and full of surprises, Harmony Of The Seas is like something from the imagination of Jules Verne.
