Detroit Museums - with kids

[dispor]

We are going to Detroit for the weekend. We'd like to use our museum passes, which would be good at the Ann Arbor Hands on Museum, Cranbrook Inst. of Science, Detroit Science Center, and the Exhibit Museum of Natural History.

Does anyone have any opinions as to which would be best with 9 year olds? I am leaning toward the Ann Arbor Hands on Museum and/or the Cranbrook Institute of Science - but that's just based on their proximity to the hotel.

Thanks!
