Carnival Spirit: 10-Night Caribbean & Panama

Galveston cruise port is the busiest cruise departure point in Texas and the fourth largest cruise homeport in the United States. The port sits on Galveston Island, a barrier island about 50 miles southeast of Houston, and it's the main gateway for Western Caribbean and Mexican Riviera sailings out of the Gulf Coast.

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.

Colon sits at the Atlantic (Caribbean) entrance to the Panama Canal, serving as the port of call for ships that transit the canal or stop before or after the crossing. The Colon 2000 cruise terminal and the nearby Cristobal pier handle the cruise traffic, both located away from the city center in secure port compounds.

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.
