What is your favorite indoor water park/resort style place in Illinois or Wisconsin? (Or within 3-4 hours of Plainfield). We used to do Key Lime Cove every couple years, but we haven’t gone anywhere in a while, just had a weekend family getaway to St. Louis pretty well ruined by a stomach bug, and we’re trying to plan something in the next couple weeks as a do-over. I’m definitely looking for something where you don’t have to go outside (so Grizzly Jacks is out). Any suggestions that your family loves (that aren’t $1000 a night )?
