Just caught up on this thread. Outstanding!
Saw a few comments about the tour of the "basement" of the Magic Kingdom in FL. They do offer an extra cost tour that includes some visiting of the utilidors, it can be hard to get reservations for it depending on how popular the time of year you are visiting is. I took the tour in early October, and enjoyed it. "Keys to the Kingdom" is the name if anyone is headed to the FL parks and considering it. (Becky is right though, while it's cool to be down there, it's not much more to see than the alleys in a shopping mall behind the rows of stores - though it's impeccably clean compared to most of those alleys There is some nice historical stuff scattered along the hallways in the form of photos and other memorabilia, though.)
