While it's possible I hosted a Disney character tour before I was born, I think it's unlikely. Since I bought a domain for my new blog, I can now more easily share PDFs and other larger files. The first thing I'm sharing via this arrangement is a 1976 guidebook produced by Disneyland's Entertainment Division for venues (such as hospitals and shopping malls) that were set to host a character tour. It's basically a comic book informing the venue of the potential pitfalls, and you can easily imagine each of the problems (poorly constructed stages, too-small dressing rooms, lack of crowd control) happening many times before. I'm sure whatever materials Disney provides now does not feel this Disney.
