Carnival Firenze: 8-Night Southern 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.

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.

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.
