I took this tour in 2002, so things may have changed, but I thought it helped me fall in love with WDW all over again. Seeing the care, detail, and thought that went into the WS totally blew me away and you learned dozens of things about the design of the exhibits that you couldn't possibly find on a sign or display as you walked around. I just saw the announcement that the tour is being discontinued, and I am sad. I highly recommend catching it while you can!
