The Wasserbahn Waterpark Resort at the Holiday Inn in Amana, IA is larger than the typical hotel with indoor water park.
This 11,000 sq. ft indoor water park features a twin body slide with a slide for beginners and a slide for the daredevils, vortex pool, zero depth wading pool with interactive toys such as a bullfrog spray hoop, geysers and arch jets, water basketball, and the requisite whirlpool.
The Holiday Inn also offers miniature golf onsite, and, a rarity among hotels, allows pets. You may want to contact the hotel directly just in case there are conditions that need to be met.
This is a great alternative for families with children of all ages. Don't expect the experience of the huge indoor water parks at the Wisconsin Dells, but if you need a fun family getaway, the Wasserbahn Waterpark Resort may be just the ticket.
