We have gone the past two Thanksgiving weeks and are going again in Thanksgiving 2014. I found the crowds perfectly manageable provided we got to the parks at rope drop and followed best days from various touring plans. We always like to do headliner rides in the am and then take a mid day break and go back to parks in the evenings for show and parades. I would not go during a peak week without a touring plan ahead of time and the ability to make rope drop.
