Carnival technically has multiple homeports, but the biggest and busiest is Miami. I learned that on my first cruise when a crew member mentioned Miami is basically the “main base” for many ships. But Carnival also has major operations in Galveston, Port Canaveral, and Long Beach. When I sailed out of Galveston last spring, the terminal felt just as organized and lively as Miami’s, and the check-in was smoother. So while Miami is their primary hub, you’ll find large Carnival operations at several ports across the U.S., which makes departures a lot more convenient depending on where you live.
