All the usual criticisms apply -- it's expensive to get in ($10 to park, $160 for 4 people, no special pricing for kids, no half day ticket rates if you get there at 2pm, etc.). Everything available to buy once you get in is expensive. There aren't many free lockers, lines are long, it's hot, the bathrooms are gross, blah blah blah. That's all totally true. But I don't think it's worse than anywhere else, and I doubt people expect to spend all day at an amusement park and have it be cheap. It's the kind of thing that we do once a year, because that's what we can afford. But once you get in there, it's fun.
But we really did have a SUPER fun day. You have to go in with the right expectations. It was really hot, so the three wave pools and the lazy river were great. I stayed with our little one while Dad and the big kids did the water slides. We didn't find much that was open for somebody under 48". That was kind of tough, my 4yo got bored with the wave pool and pretty cold after about 30 mins. The water was cold -- felt good to me in the heat, but it was pretty chilly for my little dude. It's a real production to go through the changing rooms (more lines), and the lockers are totally full. Plan to either haul a big bag around, or else take a coverup to toss on and off, since you can't ride rides in just your beach clothes, and be squishy for part of the day. Or do your rides first, then go to the pool at the end.
There are a handful of rides for kids under 44", the very best being Zach's Zoomer (40"). My 4yo absolutely LOVED LOVED LOVED it. Pure, unadulterated exhilaration -- the whole trip was worth it just for the look on his face. Even the big kids (8, 11) enjoyed the "baby ride" because he was having so much fun. There's no putting him back on the fire truck that goes around in circles after that. He also loved the Frog Hopper. And he liked "driving" the cars around, but he was mad he couldn't go with the big kids in their car -- too short! Had to ride with an adult. That was about all we found for him, though. The big kids split off with Dad again to do a few thrill rides, but not many as lines were long. I'm not sure I'd take him back until he's over 48", honestly. But even so, like I said -- we were there to have fun, and that's exactly what we did. Everybody was exhausted at the end, but it was a happy tired.
