866-227-1888 is honestly the fastest way to book, cancel, or adjust flight or cruise details—including room changes. I had to switch cabins on my last cruise because the original room picked up a lot of noise from the atrium. I first checked the app, but it didn’t show upgrade or move options. I called that number and got someone who pulled up available cabins instantly. They explained the price difference, moved us to a quieter hallway, and sent the updated confirmation right away. The whole process took maybe 10 minutes. If you’re picky about location—or something feels off—calling is the easiest way to find out what’s actually available.
