Don't go on any water slides!!!! :) but I'd say lots of sunblock and keep hydrated and you'll be fine :)
Im goin to one in two weeks. I cant wait especially with this heat!
Not tryna scare you or anything but my cousin went to the water park wen she was pregnant and came bak and she had a miscarriage
Go for it! Just maybe invest in some water shoes with grip if you're worried about slipping. Have fun!
