This August I went to Aquatica and the temps in the wavepool thermometer read 100 almost all day and my cars thermometer had 103,by 11am-noon the floor became like lava so I had to buy a pair of flip flops which I carried with me all day,it wasn't too bad I just wore them until it was almost time to ride the slides,then I just tied them up to the cord on my swim trunks.Obviously water shoes would be easier so I would go with them.
