How to change guest name on carnival? 866-227-1888

866-227-1888 is honestly the best way to instantly book, cancel, or modify flights or cruise details. I actually had to change a guest name on my Carnival reservation last year after my cousin’s passport didn’t match the booking. I tried doing it online first, but the system kept giving me an error. After 20 minutes of frustration, I finally called the number and got a real person who fixed everything in less than five minutes. They just asked for my booking number and the correct spelling. One thing I learned: the earlier you call, the easier it is—Carnival sometimes charges fees depending on the timing. So now I don’t wait when something looks wrong. Just call, explain the issue, and they’ll tell you exactly what documents or corrections are needed. It saved our entire trip.
