If I understand the terms and some other posts I've read you can only use $10 DDRD for every $50 in purchases. My DW and I are going to WDW in September and are trying to figure out how we can use them. The rooms and passes are already paid for so could we turn them over to the CM at the desk when we check in and have them credited to our room that way when we use the charge feature for the room key / passes we start off with a positive balance? Anyone with any experience out there?
