One of the places we visited in Michigan was the Grand Rapids Children’s Museum (GRCM), 2 levels of fun stuff for the kiddies.
We have also visited the Children’s Museum in Lincoln, NE. If I had to compare, I’d say that we preferred the Lincoln CM, there seemed to be a bigger variety of things to do (lots of big impressive things, too, like making a hot air balloon go up), a lot more vehicles to pretend to ride (car, motorcycle, etc.), and the facilities seemed to be in better condition overall. But, we did have a couple of hours of fun at GRCM.
It was very busy on the day we visited, lots of day care groups and other families (we were there with a group ourselves). The noise was a little overwhelming for my special needs kid. He did find some things he enjoy, as you can see. The girls both had lots of fun, but there wasn’t much there to interest the 12-year-old.
Optimally, I’d recommend it for ages 2-9. There’s enough there to keep them busy for a couple of hours. Thursday night is family night and you can get in for $1.50/person between 5pm and 8 pm (a super deal compared to their regular prices).
