Oceania Allura: 12-Night Caribbean - Southern

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 Cayman is the largest of the three Cayman Islands, a British Overseas Territory in the western Caribbean known for Seven Mile Beach, exceptional diving, and its role as a major offshore financial center. George Town serves as the cruise port, but there's no pier large enough for cruise ships.

Falmouth's historic port was purpose-built for mega-ships and sits in a town known for its well-preserved Georgian colonial architecture. Popular excursions include Dunn's River Falls, bamboo rafting on the Martha Brae River, and Montego Bay beaches.

Known as 'One Happy Island,' Aruba docks ships at the port in Oranjestad, just steps from the colorful Dutch colonial architecture and Royal Plaza Mall. Eagle Beach and Palm Beach offer powdery white sand, and the island sits outside the hurricane belt.

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.

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.
