Our 180 day mark is this weekend, and we want to do Mickeys Backyard BBQ this trip... I know that either full playment or the dining plan is due when you book it... we are DVC and havent added the dining plan on yet, was going to do that like 2 months before the trip. So my question is this: if i pay in full for the ressie now, when I do add the dining plan, will they reimburse me?
