Water is COLD!!!!
There is no reason the water should be maintained at 74 degrees when its 110 outside. Yes, I checked it with an IR gun I just so happened to have in my car at the time. Makes people want to take the drive all the way to the other water park in Henderson where the water is definitely much warmer.
Edited to add:
So I brought my IR gun to that other waterpark in Henderson and it measured the water temperature to be 83 degrees, well inline with what other outdoor pools in the valley should be this time of year. Wet & Wild is keeping their water artificially cold for some insane reason. I'll be buying waterpark season tickets next year, but it won't be for here.
