We usually go every august, but we just got back from our april trip and I think everyone in our family wants to go this time of the year now. August is very hot and humid. It takes a toll on our one ds asthma. You should get to the parks early and leave by noon for an ac and swim break. Return later when its cooler. Bring a water bottle, keep hydrated, wear light colored clothes, bring lots of sunscreen, hat, mister fan etc. I usually make gatorade and bring it into the parks. This past aug. was just too much rain. Bring your poncho, extra socks etc. I even had the ds wear their water shoes into the parks once as the sneakers were still wet. We even had to put up with the tornado warning this time. It was more rain then we have ever dealt with. Be prepared to leave your pool in a hurry when the storm rolls in. You really dont feel like eating too much with the hot temps. Just always have a rain plan and you should be ok. If you plan on doing a water park get there as soon as they open. By 11 they could close and dont reopen until 2-3. Also chairs run out by 11.
