World Waterpark is the largest indoor water park in the continent, by far, under one roof (more about that on the next page). Unlike all of the other parks included in this feature, however, it is not a water park resort. A standalone water park, it is one of the attractions at the West Edmonton Mall (which also includes Galaxyland, an indoor theme park). But the mall does offer some onsite hotels, so it could be argued that the mall itself is one giant resort.
