In the mornings, the buses stop at the BWV and then the Swan & Dolphin Hotels. The BC/YC & BCV are on another route.
In our experience, the only time the bus stops at all the resorts - BC, YC, BCV, BWV, Swan & Dolphin is during the middle of the day. It's been a few years since BWV have had to share with the BC/YC & BCV in the mornings or at park closure.
