Who has been there in early May??? How were the crowds??? how is the weather? Is it an overal nice time to go?? Also how busy is mothers day weekend??? Thanks for any reports!

I went around the 2nd week of May last year and the crowds were great, usually 15 min waits except for AK. The weather was also nice, it got a little hot and humid but I'm from MS so I was used to it.
We didn't even blink, just ponied up for the $18 misting fans. 
We were there last May as well. I'm surprised you considered it hot and humid. We are from the far north, we loved it, and we are not fond of really hot weather. It was in the low 80's every day. Great in the water parks, and great for a night time swim.
I have been to Mississipi once, in late June, and that was very hot and humid!
I agree with you on the crowds though. It is a great time of year to go.
