The waterpark design-build firm of Neuman Group, a partnership between WTI and Neuman Pools, Inc., worked with the existing Zehnder's ownership team for a second distinct waterpark on the Zehnder's Splash Village Hotel property. The new park, with a retractable OpenAire roof, is officially named Atrium Park. This park is packed with excitement, including thrilling water rides, a zero depth entry activity pool, an action river and various fun family aquatic activities. The 12-foot-by-12-foot private poolside cabanas are designed to accommodate up to 10 guests each, with various poolside amenities like a personal refrigerator, phone, safe and more.

The original waterpark, now called Splash Park, is connected by a short walk through Splash Village. Designed and built by Neuman Group in 2005, this 20,000-square-foot waterpark area features a lazy river, whirlpool spa, 400-gallon dumping bucket, water geysers and sprays and a four-story tube slide.
