Just curious, if we book a moderate and after checking in, we decide we want to go back to a deluxe, can we switch resorts (if there is availability) at that time? How would that work as far as payment. Would you just pay the difference on a credit card at the time you check in the new resort or just what would need to be done? Please don't flame me about not being sure before we go. It's not just me going, there is another couple also.
