A phone call to Carnival should get you the information you need. We have called in the past to get a record of the ships we have sailed and our past guest number. There was no problem. Good luck and enjoy your cruise.
Thanks. I just spoke with my TA and he called Carnival and got the number for me. What a great TA!!! Anybody looking for a great TA, let me know and I'll gladly pass on his name and number. He's a lucky find..
