Following along because we're going to WDW in early June for a week. We went to WDW at that same time of year in 2018 and I've never sweated so much in my entire life. LOL.

We're from AZ, but trust me when I say this...FL heat is totally different! Of course, I HOPE that masks won't be required come June, but I'm going into this trip EXPECTING to have to wear them still. My plan on how to cope will involve:
- ADRs at mid-day every day
- afternoon breaks at the hotel to unwind & swim
- 1 cooling towel per person
- 1 of those expensive WDW battery-operated fans per person (they worked way better than the battery fans we'd brought from home)
- 1 folding fan per person
- take frequent breaks at the locations where you can take your mask off (cooling stations? I can't remember what they're called)
- go in EXPECTING that we won't be touring commando style this time
- EXPECT to have a slower, more leisurely trip
- maybe do ADRs for dinner as well
Edited to add:
- bring extra masks each day
- force everybody to drink water a lot more than they usually do
