I'm traveling next week and am 97% certain that someone will be joining us, but won't know for sure until the day before (long story and irrelevant). My dilemma is - I have the DDP added to our reservation. I called dvc member services and they said I'd need to add the additional person 2 days before so that the dining plan payment processes. I didn't think to ask - what if I add them and they don't come? Will I be able to remove them off the res and get my $ back or am I stuck with all those extra dining credits for 6 nights?
