INSIDE EDITION's Exclusive Tour of Disney's Largest Cruise Ship

Mariah Carey and husband Nick Cannon christened The Fantasy, Disney's newest cruise ship––and INSIDE EDITION got a sneak pee before any passengers got on board.

The spectacular black and gold ship stands at 1,015 feet long and is the largest in the Disney fleet. It can accommodate up to 4,000 guests.

The ship is very kid-friendly. Inside, there's a spa just for little princesses. There's also a kids disco with an interactive dance floor.

There is also huge water slide called the Aquaduck.

INSIDE EDITION's Megan Alexander took a test run. The one of a kind water coaster at sea is the length of two football fields. It went all the way around the floating magical kingdom.
