We're Castaway Club members and when we booked this coming cruise with Dreams, I sent e-mail giving Donna our Castaway Club membership numbers to make sure it was noted on our reservation. She wrote back that she had checked with Disney and they already had made a note of it because it came up on their computer when Dreams made our reservations. Just FYI that this is what happened with us. I thought it was pretty cool that the computers were talking to each other. Not something that always happens.
