Hi! I have a friend leaving on the Dream on Sunday. I'm thinking of asking her to book a dummy cruise for me. Can she just book it for 1 person at the cheapest time and I change it to fit my family? Does that mean I would need to give her my credit card number or can I give her a check? Also, does my travel agent information have to be added when it's booked or can she take over the reservation after its booked? Thanks in advance!
