We went last year at that exact time. Sorry, but it was really hot and humid. It did rain often, too. I think there was one day of comfortable temperatures with low humidity. BUT, I'm from Oklahoma and am used to hot and humid so it didn't bother me at all. (well, maybe not "at all") In fact, I'm going again at the same time this year. Couldn't get DH to go again, so he is graciously (lol) allowing me to go with a friend because of the great rates. My 5 year old son would kill me if he knew where I was going. Think the WDW souvenirs wil give it away, lol?
