Not sure where you got those building numbers. The buildings are: Casitas 1, 2, 3, 4 and 5 Cabanas 8A, 8B, 9A and 9B Ranchos 6A, 6B, 7A and 7B If you paid for a preferred building, you could get Casitas 1, 2 or 3...all close to the main building (food, registraiton, gift shop, etc.) and a bus stop. Cabanas 9B is very close to the bus stop and main building. As a breast cancer survivor myself (five years this February), I remember quite clearly the fatigue. Hopefully by the time you go it will be better.
