Midwest folks, chime in!

My family does at least one week long water park trip a year, looking to bump up to twice a year. We're from mid Michigan, have done both Frankenmuth parks, Castaway Bay, Kalahari, Great Wolf Lodge, and the water park at Michigan Adventure. Looking to branch out a bit, not looking to fly but driving trips within about 7-8 hours are acceptable to me (I like to drive 🤷‍♂️). My boss has recommended Wisconsin Dells, I see there's a few there but not quite sure where to start. Thanks in advance 👍
