The New Concord Inn in the Wisconsin Dells is a standard hotel in a good location near Tommy Bartlett's Robot World and Noah's Ark.
Best suited for kids 10 and under, this family-oriented hotel features an indoor water park area with a 2 small slides for tots, a larger slide for older kids and a tree fort play structure. The outdoor water pool area offers a small slide, and a toddler wading pool with a spraying water fountain.
If you have younger children, this is a nice alternative to the large indoor water park resorts, which can be very crowded and overwhelming to small children (and some adults!).
