Your best bet is to try and get something near the main elevators, no matter where you are you still have to go through the BC lobby to get to SAB.
It's about a 5 min walk.(10 min from the far end of the villas) The quiet pool is close from anywhere.
If you let me know what kind of room your getting I could give you some room numbers to request, but your chances of getting one are basically just luck.
I do love BCV, I bought sight unseen before it opened and have added on twice. If it was up to me I'd only stay there, but DS and DDIL would like to try Vero Beach and VWL in the spring so that will be my first try of another
DVC resort.
