We booked a dummy date while onboard the magic last week and I have a couple questions I didn't think to ask at the time. We designated Dreams Unlimited as TA, so when I want to re-schedule do I call them directly? Also, the dummy is for a 3-night and we will surely do a 7 or 8-night. Will my Disney OBC from booking onboard be $100 since we initially set the reservation for the 3-night or will it be $200 after changing? Thanks for any feedback you have! The reservation desk always had such a long line while onboard, I am so thankful we were able to get this reservation.
