My coposters are neglecting to tell you that holding a room reservation does not gaurantee you a discount to your current reservation. There has to be availability at your resort and for the room level you are holding. If there is a matching availability, then yes you will get the discount. Holding a reservation takes that room out of the availability pool. Holding your reservation at rack rate can go in your favor or can go against you at the same time. If you choose to do this, then remember, you may not get the resort you want, so you should have a backup plan ready just in case. Most folks book a room they can afford and at a price they are willing to pay. If and when the AP discounts come out, they either try to stay put at a discount or move up to a better resort. You mentioned December, but no dates and what resort you're looking at.
