That's the way I've always experienced it-for every theme park except MK the bus stops at BWV, Swan, Dolphin, YC, BC. For MK, theoretically there's a seperate bus/seperate bus stop for YC/BC and BWV/Swan/Dolphin. However, one time when I left MK, I watched the bus for BCV pull away from the bus stop. I thought I'd missed it, but surprisingly the same bus then went over to the BWV bus stop so I ran over there. I asked the bus driver about it and he said that when times are slow, sometimes the same bus will go to both bus stops, then do the entire BWV/Swan/Dolphin/YC/BC route. I think that's very unusual, though, since it's only happened to me once in 8 trips to BCV.
