How do I add my booking number to carnival.com?
In order for a booking number to successfully be entered in carnival.com, the
following fields must EXACTLY match the information in the Reservations system.
Guest's Last Name
Booking number
Ship
Sail Date
In the event that you feel all the data you entered is correct, you may want
to contact your travel agent or 1-800-Carnival (if you booked directly) to
double check if there is a discrepancy in your last name spelling and/or
booking number you were provided.
NOTE: Presently you can only add individual booking numbers. Group booking
numbers cannot be added at this time.
