We just got back from a week at Saratoga staying in the springs bldg, was very convenient to the themed pool and food court but it is also the last stop on the bus schedule unless you are returning from Downtown disney in which case you are the first stop. Saratoga has 4 stops, I would strongly consider the Grandstand, it is an easy walk to the themed pool, food court and Guest Services, and has a nice pool on site that you can enjoy if you do not wish to go to the main pool.
