Water, water, water. Cooling towels, and being able to admit to yourself that you need a break. Take one! Head back to the resort, nap, swim, shower, nap a little more. Make sure you do eat something, nothing super heavy, but hot and hungry quickly becomes hangry. We have misting fans that we bought there a few years ago that we take with us every time and just refill at water fountains. Those help a lot. Lots of folks have mentioned the free water in the restaurants. We typically go in June, so while it isn't the dog days of summer yet, it is still 90s and humid. Just be prepared for it and know that there are lots of avenues to get out of the heat. Enjoy your Birthday!!
