Seven Seas Grandeur: 10-Night Caribbean - Western

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.

Costa Maya cruise port sits on the southern tip of Mexico's Caribbean coast, about 150 miles south of Cancun and close to the border with Belize. The port is not a city.

Belize City is the largest city in Belize, a small Central American country on the Caribbean coast known for its barrier reef (the second largest in the world), jungle ruins, and laid-back culture. The city itself has about 60,000 residents and a rough, unpolished feel that can surprise passengers expecting a typical Caribbean port.

Roatan cruise port serves one of the Bay Islands of Honduras, a Caribbean destination famous for some of the best scuba diving in the Western Hemisphere. The island sits along the Mesoamerican Barrier Reef (the world's second-largest coral reef system) about 40 miles off the Honduras mainland.

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.
