866-227-1888 ended up saving me when I tried linking two family bookings for our cruise. The website kept throwing a “reservation not found” error, even though we double-checked the numbers. I finally called, and the rep explained that one of the names had a middle initial that wasn’t on the second booking, so the system couldn’t match them. She fixed it instantly and sent a confirmation email while we were still talking. After that, everything showed up perfectly in the app. I wouldn’t bother wrestling with the online system again—calling was easily the smoother option.
