The number was buoyed in large part by the debut of Carnival’s $85 million Amber Cove port project in Puerto Plata, which has seen an average of 5,000 cruise visitors arriving weekly to the area.

The first U.S. cruise ship in nearly 40 years crossed the Florida Straits from Miami and docked in Havana Harbor on Monday.

Germany's Hapag-Lloyd Cruises is sending its EUROPA 2 to Cuba for the first time on two sailings in October and November of 2016.

The CEO also spoke of the anticipation many people feel about going to Cuba, an enigma to many Americans because of the travel ban.

Right now it is only Fathom’s Adonia that has clearance to dock at Cuban seaports. Over time other brands would be going to Cuba as well.

From November 21, Celestyal will sail seven-night all-inclusive cruises, which include two days in Havana, and a call at Maria La Gorda, Cienfuegos and Santiago de Cuba.
