We were at WDW last yr the Sat after Thanksgiving thru the next Sunday and crowds were pretty light. AK was closing all the FP machines by early afternoon because they weren't needed, when we used FP at spacemountain one afternoon the only people we passed in the standby line were those slower than us, we were walking onto Test Track our 1st Epcot evening and they skipped the holding room with the film and had everyone walk right thru, the Sat after Thanksgiving the whole left section of seating at Fantasmic was empty for the 2nd show. The only place we felt the crowds were MK Main st anytime close to a parade or fireworks, trying to find a spot for Illuminations, and I thought Epcot had alot of people just on the walkways which seemed odd since this is one of the bigger parks where you aren't suposed to feel the crowds as much. This is a great time of year to go for low crowd levels.
