The TS places are full, the parks are empty... we stayed over Labor day weekend last year, on tuesday after the holiday you would think someone flipped a switch and everyone was gone. At noon that tuesday we walked on Buzz, and did not have to get off as there was no one in line. Around 2pm we rode BTMRR 5 or 6 times I think, in the front car, with out getting off. AFter that many times we were done riding, but someone did show up that wanted the front car, so we moved on.
The next day, over the couse of the day at Epcot, the longest wait for Soarin' was 10 min.
The only thing that is wonky that time of year is that Sprectromagic is not every night, and wishes runs early.
