I have stay all over the property and you will find that all are well served for the race. I think the Pop or Animation may be the better economy choice as they are closer to the expo as well as close to the race. Plus the resorts are a little smaller than the All Star complex. Any of the moderates will work fine if that is in your budget range. If you have a strong desire to stay at a particular resort, I would book as soon as 2014 reservations open. That will kepp you from being blocked out. The caveat to this is that you can always rebook once any discounts are announced. The rebooking will not cause you to lose your room. Keep an eye on sites like Mouse Savers to for any discounting that may occur. Oh, Make your reservations through Central Reservations and not the marathon reservations. The Central reservations (407-WDW-Disney) folks will have deeper discounts if they are announced.
