Seven Seas Mariner: 15-Night WESTERN CARIBBEAN

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.

Tortola is the largest of the British Virgin Islands, a mountainous, lush Caribbean island where Road Town serves as the capital of this British Overseas Territory. The cruise port at Road Town Pier Park handles two large ships simultaneously (up to 180,000 GT).

Martinique gives you something most Caribbean ports can't: an actual piece of France in the tropics. This is a French overseas department, so the bakeries are real, the wine is good, and the Creole cuisine draws from both metropolitan French technique and Caribbean soul.

Barbados cruise port is in Bridgetown, the capital of the easternmost Caribbean island. Bridgetown Port (Deep Water Harbour) sits just outside the city's UNESCO-listed historic center, with modern terminal facilities including 21 duty-free shops, restaurants, car rental agencies, and a tourism office.

You've probably seen photos of Willemstad even if you don't realize it: that row of pastel-colored Dutch colonial buildings along the Handelskade is one of the most photographed waterfronts in the Caribbean. It's been a UNESCO World Heritage Site since 1997.

A diver's and snorkeler's paradise, Bonaire is surrounded by a protected marine park with over 80 marked dive sites accessible from shore. The island's laid-back atmosphere and flamingo sanctuary at Goto Lake offer a quieter Caribbean experience.

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.
