Offering features you won't even find on land, these ships are so advanced that they have their own robot bartenders, SkyRides and F1 simulators.

Spa lovers will want to head straight for The Spa on Viking Cruises' Viking Star as the 870 square-metre space features eight treatment rooms, including a spa suite with a whirlpool, a wet area with a thermal pool, a hot tub, a steam room and a Snow Grotto. The Snow Grotto is an attraction in itself and allows you to partake in the Scandinavian ritual of going from hot to cold temperature extremes (also known as contrast bathing) in a very cool setting.

For those who like to be treated like a VIP, Regent Seven Seas Cruises' Seven Seas Explorer has one of the largest suites at sea at over 3,875 square feet. The Regent Suite is as luxurious as a cruise cabin gets, with two plush bedrooms and an in-room spa retreat (a first at sea) which combines a personal sauna, steam room and treatment area.

Then there's all the fun waiting to be had: tallest slide at sea, anyone? The Ultimate Abyss on Royal Caribbean's Harmony of the Seas stands 150ft above sea level as a pair of side-by-side slides that release adrenalin junkies into a chilling 100ft drop which twists and turns in a snake-like movement. The hair-raising ride is not for the faint-hearted!
