The 4,000-passenger Disney Dream was christened last week in Florida. The cruise ship has two large theaters and about a dozen other venues that can accommodate meetings and group events. Unique features include virtual portholes on interior cabins, an AquaDuck Water Coaster and "enchanted" works of art that interact with guests. The ship will sail alternating three- and four-night cruises from Port Canaveral, Fla., to The Bahamas and Disney's private island, Castaway Cay. During the summer months, the ship will alternate four- and five-night itineraries with two stops at Castaway Cay. This is the third ship in the Disney Cruise Line fleet.
