The Imaginarium is a great place for kids to spend a rainy day or a cold day. There are lots of activities to engage children of various ages. I only have one complaint -- parents have to pay too. I would go much more often (especially now that they are in Cool Springs) if the parent did not also have to pay admission. Why do I pay? I'm not in the dinosaur pit.
Pros: good for multiple age, contained enviornment
Cons: parents pay admission, poor lighting, safety concerns
