We have been there for the third week in August twice now...'03 and '04. The first time was hot/humid and the crowds were moderate. This was due to pretty good deals for rooms at WDW. Then last summer, we hit Hurricane Charley. The weather after he left was brutal. It was much worse than the year before. The humidity was really oppressive. It rained somewhat every day but not the deluges we had in '03. The crowds grew as we went further into the week. Evidently the schools were closed, due to the hurricane, and once people could get around, they headed for the parks!! There were a ton of locals there that normally would have been at work/school.
