We are sailing on 09/23/07 with intentions of booking on-board for the 10/25/2008 double dip. We are booking three rooms because we are taking some extended family members as a gift. I know I can book onboard to get the 10% discount and the $200 OBC per stateroom. Can I use my Disney Visa to get an ADDITIONAL $50 OBC? Will that apply to each stateroom? Can I then transfer all three reservations to DU (before paid in full) to get an ADDITIONAL OBC per stateroom? If so, does anyone know what DU is offering for an OBC for the 7 night cruises? I'm wondering if this is all possible because it sounds too good to be true! Thanks!
