If this has been posted before I apologize, but I found this pretty cool video from last September on YouTube (I would not be shocked if someone here made it) of a complete walk-through of the magic kingdom starting at the opening ceremony. It is a long video, but gives a pretty good look at everything without much of a crowd getting in the way.
