I remember driving to BW in Oct. 2000 for dinner and evening entertainment. I don't think there was a charge to self-park? Maybe a charge for valet?
Anyway, park there and proceed through the main BW entrance (by-pass hotel lobby). You will exit onto the BW facing the lake. Flying Fish is to the right.
Also, short walk from EPCOT-WS. Can walk from MGM, Swan/Dolphin or Yacht and Beach. All are further away than BW parking.
