7 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.

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.

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.

Cozumel cruise port is one of the busiest in the Caribbean, with multiple ships docking on the island every day during peak season. Cozumel is a flat, laid-back island off the eastern coast of Mexico's Yucatán Peninsula, and it's been a cruise staple for decades.
