I'm from LA and I visit Fresno every summer (family). I have to say, we had a great time at the waterpark! I have 3 kids, 1 of which is too small for the big slides and I had a blast with my little one at the kiddie area. Yes, it's hot, but we found plenty of shade. Maybe the other reviews are from previous visits, but we found shade to eat under and even air conditioned areas to hang out in.
