Never request a specific room number because if it is occupied, you have nothing for a request. Just tell them what you would like. The elevator comes down to the lobby, so it doesn't really matter where you stay. It's a small resort, no walk is too far.
I think all the rooms have a patio, some smaller, some larger. BCV is quiet and set back from the Beach Club, so while it might be closer to the parking lot, it's a little distance from the bus stop, Stormalong Bay, Epcot, Disney Studios, etc.
