Great Wolf Lodge is one of the best indoor water park resort chains for families, with several locations across the country (our favorite being Great Wolf Lodge New England). Two new locations in Bloomington, Minnesota (at the Mall of America) and Gurnee, Illinois (the former Key Lime Cove Indoor Water Park) are in the works.
All resorts feature indoor water parks so massive that you won't even miss the outdoor water parks open during the warmer months. You'll find multi-story forts, 1,000-gallon soaker buckets, wave pools, lazy rivers, waterslides of varying heights and speeds, raft rides, whirlpools, kiddie pools and just your average pool -- all indoors at a balmy 84 degrees Fahrenheit. Lifeguards are plentiful and life jackets are available.
With families in mind, resort rooms can accommodate large groups, and onsite restaurants, arcades and organized activities keep you from leaving the lodges to brave wintry winds.

Sure, Fallsview Indoor Waterpark has its share of waterslides, pools (indoors and out) and spraygrounds, but what we love most is that it's connected to a few hotels -- meaning you don't have to step outside when it's time to leave! Consider a stay at the Skyline Inn, connected to Fallsview Indoor Waterpark via sky bridge. We also love that the indoor water park is so close to Niagara Falls!
