On our last trip I booked a Free Dining Bounceback for July 2018. I don't really expect to keep it because our preferred resorts were not available, so we ended up paying more than we planned for POR Royal guest rooms. I got the best I could just in case nothing better comes up later in room-only offers. When we got home, I realized that they did not upgrade the QS dining plan on the room we booked as requested. Is this something I have to call the BounceBack number to correct, or can I do it directly through Disney later. Do I have to do it now, while the FD BB offer is still available, or can I change the dining plan later, once we get closer to the trip and know for sure which plan we want.
