This is the most amazing place I have taken my daughters (2 yold and 9 mo.). I visited here last week and was shocked at the fun outdoor children's garden. First of all, it is a mix between Chuck E Cheeses and Six Flags BUT it is clean, only for kids, and educational! There are so many neat water toys, treehouses, huge sandboxes and a place to have a tea party. The cafe was delcious inside and had great kids meals. I will be back next time I am in GR.
One of the reasons that I think it is so great is that it isn't used so much that it is worn out. It is a little costly to go here on a regular basis unless you have a family membership. Otherwise, it would be run-down.
