Hello N.,
Mother of a 5 yr daughter & 7yr son - We went to Wisconsin Dells over the 4th July holiday and had a great experience. While there, we saw the Kalahari Resort and visited. As a guest, you had to pay regular prices, but it was awesome. Needless to say, we are going back to stay at the Kalahari Resort, August 21st weekend. This is an awesome establishment, it has the indoor and outdoor waterparks, the indoor theme park (bowling on the second level, toodler rides, carousel, much more), IMax Theater attached, restaurants, and different rooms/floorplans. We are parking the van and not moving it until time to leave. You can go to KalahariResorts.com and they have some reasonable bundle packages for the family. I have not been to the one in Ohio but the Wisconsin is totally awesome.
If you like I could check with my travel company to see if there are any deals as well. If you are interested just send me a not back.
