Sounds like quite a special birthday is in the works. I haven't seen any AP rates released for that time period but I would check mousesavers.com as all discounts should be listed there. I'd hurry and make some reservations though as things are filling up pretty fast at all the resorts and that is a pretty busy time. As far as where to stay, a lot depends on what kind of resort you think your daughter would enjoy most. Certainly she would love just about any of the deluxes with the GF making her feel like a real princess and the Poly would be quite a relaxing tropical vacation with easy access to the MK from both. I love the BWI and the atmosphere of the whole boardwalk area. My biggest concern right now would be not disappointing her by not being able to find any rooms for those dates at WDW. I'd call first thing tomorrow and see what they have available and get something booked to be on the safe side. If you are unable to get anything, consider a delayed birthday celebration as the week after New Year's should offer a greater chance of discounts, smaller crowds and a wider availability of rooms. Once you do that you might check out the dining forum and ask for some suggestions for her birthday dinner and get that PS made asap. Good luck and let us know what you were able to get reserved.
