I recently made a reservation for my mom and I to take the kids to CR this summer. My mom says she remembers some problem using the Disney Visa Reward card at check in last time. She says they said it needed to be part of the reservation or something. This was about 4 years ago. I don't remember any such problem and have used mine in parks and for DCL. Is there a trick to using for a room package? I am planning to just apply it to the balance at check in instead of earlier b/c I worry about losing points should we have to cancel or change plans. But it is $800 worth of points and I don't want to miss the chance to use it. What do you think??
