The Bavarian Inn Lodge in Frankenmuth, MI, is not an 'indoor water park' in the truest sense of the phrase, but it offers enough indoor amusement to warrant being included in this list.

As one of the first hotels in the country to offer an indoor entertainment facility, the Bavarian Inn Lodge, is home to 5 indoor pools including a zero-depth to 18" depth pool for babies, a "current" pool with waterguns, a relaxing large play pool, an adult only pool and a waterfall pool. The large family fun center features an indoor miniature golf course, a large arcade center, and a two-story children's play village.

If you are heading to Frankenmuth with kids, the Bavarian Inn Lodge is the place to stay. Nestled on the banks of the Cass River, the Lodge is just minutes from River Place shops and downtown Frankenmuth - Michigan's #1 Tourist Attraction.
