So help me prepare mentally...we are booked to go Nov 18-20, Sun thru Tues before Thanksgiving. When I looked at crowd calendars it gave these days slightly less crowded than the day before Tday and the days right after...My DD has school off the whole week of Thanksgiving, which I'm hoping is not the norm for most schools. 
So in your opinions will be be totally insanely crowded??
