I've heard it is really hot in the summer, specifically at DL. I'll be there the second week of July. Is it hot? Most will probably say "yes," but I reside in Florida. It's not only hot, but it's also humid. I'm looking for a comparison of some type. I've been to WDW in the summer and vow to never do it again.....by the time you reach your first ride you're soaked in sweat...yuck. Will I have the same experience at DL and will I need a sweater in the evening? Any info would be greatly appreciated.
