I don't really like water parks, so I don't go to many, but I think this is a pretty good one. I've probably been 6 times or so and I don't remember it ever being too crowded. I don't know when you are coming to OKC, but tomorrow (7/31) night they have their "Dive-In Movie" At 8:00pm you can get into the park for $10 per person and watch Transformers while floating in the wave pool. You could go check it out and watch a movie for relatively cheap. If you like it, you could go back. If not, you could go to Frontier City which is more like Six Flags, but definitely smaller. There is also a Celebration Station nearby that has bumber boats, go carts, mini-golf, etc. If you need any help with directions just let me know.
