Given that the BW is the last stop on the MK bus trip in either direction, it is sometimes convenient to get off at the Swan bus stop when returning from the park. A short walk through the hotel and over the bridge takes you to the BW. I have done this while my DW has stayed on the bus all the way around (with stops at Swan, Dolphin, YC, and BC prior to the BW). I had been back in the room for about 15 minutes when she arrived.
