I suggest going bare foot if possible at the water parks. I bought two pairs of water shoes to use at the water parks and ended up going bare foot because the water shoes were not very comfortable in and out of the water (plus you will have to take them off and hold them for some of the slides). And even in July I walked around fine bare foot and I never ever walk around without shoes, so if the cement was hot I would not have been walking around without some sort of shoe on. I ended up putting my flip flops and water shoes in the locker and going bare foot, then putting my flip flops back on when I was ready to leave.
