Back when Disney MGM studios had recently opened they had a 6 AM opening. We were staying at Caribbean Beach, and happened to see a temporary sign in the lobby saying that it would open at 6 AM. So we got up at 4:30 or so, got all ready, opened the door, and saw it was pouring! But we caught a bus in the pitch dark of early AM and got there for a 6 AM opening! I can't recall if it was busy or not, but I can't imagine it was. I remember my little brother leaving our umbrella on star tours first thing, and being annoyed with him because then we couldn't move on but had to wait for the next ride to end to get it. I have never seen anything like that again, but I will always remember that A framed sign with the 6 AM opening on it, I still think it was pretty neat and wish I remembered more from it. We never did find out why they did that, how often it happened, or anything. We just saw the sign, got up early the next day, and went!
