We have three kids ...all boys ... 4, 2 and 1. This place was great. We've visited over a dozen Children Museums from DC to Maine and NH. This is the best by far. What a gem. We love the one in Philadelphia as well, but this one has so many unique things for the kids to do. We planned on staying for a couple of hours and spent almost the entire day there. The vertical kid maze was pretty neat but honestly too many nifty things to mention. As an aside, we presented our Museum of Science Boston membership card hoping they had some kind of association and get a couple of bucks off ... Instead we got free admission for the entire family. Nice!
