First off, this is a good rainy day activity. The two kids we brought really enjoyed it. That said, the museum does not have the most inviting entrance area. It's a narrow hallway with steep walls so you feel a little intimidated, then opens to the first room with a billion kids. Once you get over it, it's a pretty good experience. It's deceptively large with lots of things to do. You can easily spend 4 or 5 hrs here. It is expensive and a little run down and ultimately 3.5 stars is more accurate. You have to pay for parking which is a private lot just for the museum. They have a subway on-site that can hold very few people and by the end of the day was dirty. We did have a good time, but just a lot of drawbacks. That said it is a fun thing to do especially on a rainy day.
