ORLANDO, Florida - Walt Disney Co rolled out a new 4,000-passenger cruise liner, joining other cruise operators in adding bigger and potentially more profitable ships to their fleets.

Disney operates several ships catering to the family entertainment segment.

The new Disney Dream, which cost more than $900 million and features a high-speed water slide that takes riders out over the side of the ship and back, docked in Port Canaveral in central Florida in preparation for its Jan 26 maiden Caribbean cruise.
