You are right, however this same day, I literally could not move in Adventurland due to the crowds--I honestly never saw anything like it except when we went one year in August (96 or 97). I did notice alot of tour groups with the yellow flags. They would grab onto each other and push through the crowds. Once or twice I just followed behind them. Anywhere we went, Animal Kingdom, Epcot, Disney Studios--crowded!!! I can't imagine what it must be like now in the Summers. I was glad we left everyday around lunch time for a break. We needed a bit of downtime after getting through all the crowds. [Also, most TS we ate they were turning away walk-in's.]
The afternoon I was in MK was Thursday, it was packed!!!
