water view room at BWI to AP rate ? Is this possible? I currently have a room booked but am now planning on picking up an AP when we arrive in Orlando (Disney stay is a week later). If I call to change the booking (assuming I can't do it online) and tell them I will have an AP but don't have it currently, will they change my non AP rate room to an upgraded AP rate room and just let me pay the difference, if any?
