5-Night Bahamas 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.

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.
