Best thing ever! I went on this tour almost every day! Not only do you get some 'free' drinks and a glass in a tin can, but if you are nice, you usually get more! I have met some of the nicest people while on this tour, and we ended up spending the whole weekend together.
The best parts are the rides that go with the history. There is a horse-and-carriage simulator and a bottle-filling simulator. You can also sit in uber-comfortable chairs and watch commercials from the past, which is funner than it sounds!
