We were there for a week, mid-August '03 and never heard a thing. We stayed in Tokelau but did wait for the bus at the bus stop many times and also walked over to TTC to catch the monorail to Epcot and never heard the racetrack. There is one bldg., can't remember the name, that does face the entry road and toward the race track that you could possible hear the noise from. But, I think it might only be on the upper floors.
