Celebrity Beyond: 6-Night Grand Turk, Puerto Plata & Bahamas

Miami cruise port, officially called PortMiami, is the busiest cruise port in the world by passenger volume. Millions of people pass through here every year, and nearly every major cruise line uses it as a home port.

Grand Turk is a small, flat island of about 4,000 residents and the capital of the Turks and Caicos Islands, a British Overseas Territory southeast of the Bahamas. Carnival Corporation built a dedicated cruise center on the island's south end, and the vast majority of cruise traffic comes from Carnival Cruise Line ships on Eastern Caribbean and Bahamas itineraries.

Puerto Plata cruise port is on the north coast of the Dominican Republic and operates through two distinct facilities. Amber Cove is a Carnival Corporation exclusive port covering 30 acres of waterfront, used by Carnival, Princess, Holland America, Cunard, P&O, Costa, and AIDA ships.

Nassau cruise port is one of the most visited in the Caribbean, with up to six ships docking at Prince George Wharf on a busy day. The port sits directly on Bay Street in downtown Nassau, so you're essentially stepping off the ship and into the city.
