My husband wanted to see the Wisconsin and we ended up spending the ENTIRE day there. We did the Spy Ship activity which I think helped keep myself and daughter interested; however, it has you going back and forth on the same parts of the ship so my husband didn't get to see the things he wanted to before the ship closed. So depending on what you want to get out of your visit..... you may or may not want to do that.
There was not a restaurant onsite so that was a disappointment and something I wish I had known.
