I'm not quite as good on Buzz Lightyear. My dad's probably one of those crazy people you've run into. He just loves all of the Disney and Universal parks there. Any excuse he can make to go, he'll take.
I remember back when I was young, when Splash Mountain first opened, I was too short, but the employee let me go on anyways. I'm the youngest in my family, and that was the last time we had the problem, so I suppose we never got to a crazy scheme like it sounds like what you've seen. Fortunately we don't steal salads, but I remember when we first took my bro-in-law to the Magic Kingdom and ate at the Crystal Palace... He loved it for the buffet
Ever done a Keys to the Kingdom tour? Somehow we managed to convince my dad to do something different for his birthday the year before this past one, and it was a unique bit of good fun, but not quite as "behind-the-scenes" as we'd like. Still, if you're that avid a fanatic, it's something to consider!
