Dells trip recommendations?

Hi, all! After seeing what Great Wolf Lodge in MN charges, I’ve decided to bring my family to the Dells for spring break this year. We have 5 kids aged 3-14.

I have it narrowed down to Wilderness and Kalahari, as I’ve heard of them and they are a lot more reasonably priced. Chula Vista as well, but I’ve never heard of that one.

Any recommendations?? On site preferred. Thanks in advance!!
