My kids thought this submarine was so-so. The audio tour included a lot of historical facts about the submarine, but the kids just aren't really into history. Being inside the submarine was cool to them and seeing how the sailors lived was eye opening. We toured the sub for a relatively cheap because we had a large family. You can get the family 4 pack for $20. A thought that was a pretty good bargain and it helped to pass the hour or so we had until our Alcatraz tour. If you are a history buff, or in the military, I would recommend touring this at least once.
