We went last year. We packed clothes for hot and cold weather. It ended up being very cold and windy. Sunday-Tuesday was not that bad--but towards Tuesday afternoon it started getting bad. Wed-Friday was horribly crowded. We made it to EPCOT 1 hour after opening and got the last fast passes for Soarin and it was for a return time of 9:00. Needless to say we did not ride it that day. Thanksgiving day at MK reminded me of 4th of July there---very crowded and hard to move around. Make sure that you have all of your ADR's already. We saw many people turned away for their TG meal--they never thought it would be a problem of being seated--there were a lot of angry people over this. HTH
