We did multiple August trips. Yes, it is brutally hot and humid. Yes, it'll rain for a bit in the afternoon. Yes, we still choose to go. Here are my tips:
1. Bring at least 2 pairs of underpants per day. Maybe TMI, but you'll sweat-wet whatever you are wearing, right down to the skin. Bras in multiples, too. As mentioned previously, things don't dry in 24 hours in that kind of humidity, even in the room.
2. Powdered electrolyte sticks, like Propel. I have trouble drinking large quantities of water and find it more tolerable with flavor. The added electrolytes are a plus as you are going to sweat a ton.
3. Frog-toggs poncho. About $6 at
Walmart. It's made of a more paper-like material than the cheap dollar ponchos or the Disney heavy plastic ponchos. I swear those plastic ponchos are like a sauna... and who needs to be trapped inside your own personal sauna when you are already in a sauna?
4. Neck fan. It blows air up onto your hairline and cools your head a bit. Yeah, it's ambient air, but moving air is cooler than still air. We don't like the mist fans.. you are already wetter than a fish, and it's too humid for the mist to evaporate and provide any cooling effect.
5. "Frozen" washcloths. Wet a wash cloth, put it in a ziplock with ice, and then put all this in a bigger ziplock and into an insulated sandwich bag. VERY refreshing to wipe down with a cold washcloth, mid-day. If this is too much bother, bring the washcloth anyhow. Get a cup of ice water from a counter service place and use that to wet the washcloth.
6. SUNSCREEN. Sunscreen STICKS for fast swipes to noses, lips, and ears when you aren't "into" doing the whole douse-down while waiting in lines.
7. Walk thru the gift shops as much as you can. They are airconditioned.
8. We plan a big sit-down meal to be part-way thru our park day. An hour or so in air conditioned splendor is rejuvenating.
9. If you MUST use the pool, search out the quiet pools. The feature pools are just too warm... it's gross, especially when you remember that about 2% of the kids in that pool didn't bother to rinse off their stinky, sweaty bodies before getting into the pool. Quiet pools usually have fewer kids in them, and are less hot than the feature pools. I never thought it'd happen, but those pools are as warm or warmer than the air- definitely NOT very refreshing.
