Our cruise/wdw vacation is directly after Christmas. We have a lot of very kind family members that have said that they would like to give us and the kids disney gift cards for their Christmas present. I am assuming to use them on board, we would have to add them to our on-board account. I am just wondering, what if we don't use it all? Does it get credited back to the wdw gift card? I am asking this because I know the kids will want to spend some at wdw and some on the cruise, and we are doing wdw both before and after the cruise. I am trying to figure how to balance it all out. Can I just add one card at a time during the cruise? I guess if worse comes to worse, I can just reload the cards with whatever should be on it after the cruise. The overplanner/worrier in me is coming out.
