We did the tour last September. It was wonderful. Our guide told us lots of stories about Walt and
Disneyland's early days (some of which I already knew, but I always like hearing them). He was so passionate about the subject, he struggled to maintain his composure at the end of the tour and had the whole group walking back down Main Street in tears lol! 'Extras' we got as part of the tour were Peter Pan, the train and Great Moments with Mr Lincoln, as well as the Dream Suite (as Walt's Apartment was inaccessible at the time). I would highly recommend this tour for anyone with a keen interest in Disney and Disney history.
A couple of side notes. I wouldn't recommend the tour for small children, or even teenagers not really interested in the finer details of Disney. It was a long tour with mainly historical stories and could get pretty boring pretty quickly for people not really interested. Also, the tour includes lots of walking and standing around, not always in the shade. The day we did it happened to be ridiculously hot and it was quite uncomfortable at times. I'd recommend booking a morning tour at that time of year, as there will always be potential for it to be hot. Also make sure to wear comfortable shoes and clothes.
