General admission is very pricy, but the group rates are very good. The upper level has a lot of information to read, so my son gets way ahead of me. They have a lot to look at and several hands-on exhibits. You can touch the stingray, and they have a play area of the locks of the great lakes which the kids really enjoy. We saw the otter program. I could watch the otters for hours, but I was sad to find the eagle was gone. There are also lovely views of the harbor. If you can gather 10 people, you have a group, but I would not go if I had to pay full admission.
