TheBest Western Kelly Inn in Plymouth, MN now offers an indoor water play area.

This hotel does not offer what I would call a true indoor water park but it does offer activities for younger children, which can be very important to parents. With 2 small slides, tumble buckets, and a water basketball area, it is a step up from a hotel with just a pool.

Interestingly, this hotel also has an on-site 211-seat theater which features off Broadway productions. This is a nice hotel, but take it for what it is (a hotel with an indoor pool play area) and don't expect it to be what it is not (an indoor water park resort).
