The 3,646-passenger Carnival Dream, the largest-capacity year-round cruise ship to homeport at the Port of New Orleans, left Monday afternoon on its first six-day cruise from the Erato Street Cruise Terminal. The vessel will travel to Costa Maya and Cozumel, Mexico, and Roatan, Honduras, on its introductory trip. Beginning Sunday, the Carnival Dream will operate year-round, offering three itineraries to the western Caribbean. The ports of call include Montego Bay, Jamaica; Cozumel, Mexico; and Key West, Fla. Before the Carnival Dream, Royal Caribbean Cruise Line’s 3,114-passenger Voyager of the Seas was the largest cruise ship to call New Orleans home. The Erato Street Terminal underwent a $2.3 million renovation to accommodate ships as large as the Carnival Dream.
