hmmm, we've been in wdw for three labor day weekends ('99, '01, and '04) and crowds were nominal... 99 was probably the worst, imo... '01 most rides were 5-20 min at mk, and '04 the parks were closed sat/sun due to hurricane frances, and empty on fri and mon... we're contemplating same time this year... we like low crowds, even w/high heat...
