Water park
With 5 indoor water parks, Wisconsin Dells, Wisconsin, is recognized as the "Water Park Capital of the World." It showcases several of America's largest indoor and outdoor water parks (see Noah's Ark Water Park). Indoor water parks in Wisconsin Dells debuted in 1994 after the Polynesian Resort Hotel built the first one in the U.S. The success in extending the tourist season and turning water park resorts into vacation destinations has resulted in tremendous industry growth. Usually resort hotels featuring massive indoor water parks that are often reserved exclusively for overnight guests, companies like Great Wolf Resorts/Great Wolf Lodge and Kalahari Resorts have branched out from their origin in the Dells to open new locations around the country. Mt. Olympus Theme and Water Park (formerly Family Land) is another huge water park in the Dells.
