We always go in August because I am a teacher and have to go in the summer. We are always at the parks at rope drop. We alternate outdoor attractions with indoor, air conditioned ones. We carry wet washcloths in a bag to freshen up with. We have misting fans. We leave the park after lunch and return to hotel for rest/swim break. We then head back to the parks in the early evening for round 2. Also, you can get free ice water at counter service locations. Make sure you stay hydrated.
