Well, shucks, we're gonna be there the same time! We went last year at this same time and had a great time.
Weather--still plenty warm. Mid to upper 80's day and about 70 at night. No rain at all year that I recall and we were there 9 nights. It was hot enough at the Halloween party that we were shedding our costumes after the photos.
Crowds--not a problem for us. We've been over Easter and July 4th and of course they are nothing like that! We have fun whenever we go...we go early and bail when the parks start filling up. Use fastpass and a good plan and you can do whatever you want!
PM me if you have and specific questions!
Have fun planning!!
