Okay, so during Spring Break our 15 year old twin boys always get to "pick" where we are going. And, for the last couple years, we have gone to The Kalahari Water Park in Ohio. Well, they decided they wanted to travel to the Wisconsin one this time due to it having an Indoor Theme Park (unlike the Ohio one). SO, we thought it was just going to be another "water park vacation" where we do nothing but that. However, now that we have taken a more expanded look at the area, we now see that this is a HUGE tourist area. So, Question: We will have 3-15 year old boys with us and what would you recommend us to do while we are there? Teen-oriented for fun. We originally was going to stop on our way back home into Chicago and stay an extra night there, but with what appears to be a large amount of things to do, we may just stay in this area another day or two. SO, any suggestions that we "MUST" see or do while in town? Thank you!
