Since 1985, when developers built the world’s first indoor waterpark at West Edmonton Mall in Alberta, Canada, the indoor waterpark market has enjoyed steady growth. According to Hotel & Leisure Advisors, indoor waterpark resorts, while not seeing the same boom in expansion as outdoor facilities, have had continued to increase in both the municipal and private segments. Europe built Blackpool in 1986, and Wisconsin Dells’ Polynesian Resort Hotel opened in 1994.
