Oceania Sonata: 12-Night Pacific Coast from Miami

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.

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.

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.

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.

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.

Cartagena de Indias is a Caribbean port city of about 1 million people on Colombia's northern coast, and one of the best-preserved colonial cities in the Americas. The walled old city (Ciudad Amurallada) is a UNESCO World Heritage Site, built by the Spanish starting in the 16th century to protect the gold and silver being shipped back to Europe.
