There is no guarantee that there will be codes for your resort stay. IF there are AP codes released, and IF they have them at the resort you want and the view you want, they will book an identical reservation to what you already have and cancel your existing reservation. Booking ahead of times usually hurts the folks waiting for an AP code, not help them. If there are plenty of rooms available, then there will be discounts. IF everyone books them and it appears they are planning on paying rack rate, there will be no discounts on the rooms. If it worked the way you described it, we would ALL book the exact room we wanted and applied the codes when they were released. The only way you can help yourself get a discounted room is to be flexible with where you want to stay. Often standard view rooms are not available and alot of times CSR and A/S Movies have no discounted rooms available. It's all a game of waiting. Since your dates are so close to Christmas, there could also be a strong possiblity that those dates will be blackout, as they are for Easter this year. Good luck.
