Hurricane Harbor is not the best place to take small children in the greater Los Angeles area. The water slides are too big. The splash areas with smaller water slides and fountains are so large and spread out it is impossible to keep track of more than one child at a time. The lazy river ride looks like the LA River, i.e. polluted. Unless you are first to arrive at the park, it is impossible to find chairs. Even on a hot day, the water is much too cold. The lines for all the rides are much too long. The food is bad and overpriced. There are lots of photographers around the park taking pictures, but when you want to check out the photos they took of you when you leave, there is only one small booth with not enough employees to handle the lines. The parking lot is too far away. And....there is still plenty more to complain about.
But -- still the kids had fun. I won't go rushing back until the kids are significantly older, but I'm glad we checked it out and it's hard to deny the smiles at the end of the day.
