I did the free factory tour and the chocolate history trolly tour. The factory tour is simulated with projections and animatronics in lieu of the real deal, but it's free and still interesting. The history tour I can not recommend enough. It's a whole biographical walk through of Milton Hersey and the township. I guarantee you will get off the trolley just astounded by Hersey's accomplishments.
