Part of Grand Geneva Resort & Spa, this family lodge sits on relaxing wooded grounds and boasts amenities like a championship golf course, an arcade and Moose Mountain Falls, a 50,000-square-foot indoor-outdoor water park. Overnight guests get four complimentary passes to the facility’s twisting slides, lazy river and heated pool. Kids will especially love climbing ropes at the activity pool and riding Avalanche Falls, which plays various songs as riders zip past colored lights.
