If you have small kids and you don't take them to the Wonderlab (and I mean more than once!), I only have one thing to say to you: Shame on you! No, it will never take the place of the Children's Museum, but then you also don't have the 2 to 3 hours of driving and the driving through Indianapolis. And it's a close 2nd for smaller kids. Your kids will have a blast, and so will you.
