None of them are very close to SAB. They are very close to the BCV quiet pool, but all far from the SAB pool. We were very close to the elevator and it was still a bit of a hike to SAB. Once you come down the elevator, you will have to walk from the Villas to the BC store area, through the lobby, past Cape May, then to the pool.
To leave your room, even if you are on a ground floor room, you will have to exit via the main lobby or one of the corridor exits.
