New Orleans’ largest year-round cruise ship, the 3,646- passenger 'Carnival Dream', has sailed on its inaugural 6-day cruise from New Orleans. The Port explains that Carnival is the port’s largest cruise operator with two ships carrying more than 400,000 passengers annually – the most of any cruise line. The special six-day voyage, visiting Costa Maya, Mahogany Bay (Isla Roatan), and Cozumel, left from the newly refurbished Erato Street Cruise Terminal, which has undergone a $2.3 million upgrade to accommodate a ship as large as the 130,000-gt Carnival Dream.
