Covering a massive 173,000 square-feet, Ohio’s Kalahari is the largest indoor waterpark in the country, designed with an African motif and a roof system that allows for year-round natural light (spring sunbathing, anyone?). Beyond its vast village of condos and spa, there’s a newer 215,000 square-foot convention center. (Because the corporate team that works together, waterslides together.)
