You definitely want to stay at the Springs. We stayed there this past October with 4 little ones and we were within a 5 minute walk of everything:
the main swimming pool, the restaurant, the cafeteria, the general store & gift shop, the bus stop, the community hall, the main lobby,the arcade, the place for bike rentals and the bus stop.
The main swimming pool is really nice; it has a very cool slippin slide, 2 hot tubs, a zero entry area for the little ones, a Donald Duck play area and best of all... a cocktail bar that serves wonderful frozen drinks !!!
Good Luck -
Joe
