As a former MGM CM (94-96), the main thing that I can suggest is bring your patience with you. I understood that a few guests had been waiting for things since they arrived in the park that day: entrance queue, food queues, attraction queues, waiting for a table to clear, waiting for the restrooms during a crowded day, waiting for a space to sit down and wait for "Sorcery in the Sky." Guests wait. And, for the few guests who can only take so much waiting before keeping their temper in check becomes an impossibility, impatience breeds impatience in others. I saw it time and again, at our attraction with an outdoor queue, especially during the warmest months and the hottest and stickiest parts of the day: one guest would lose their cool, and another guest not too far away (in line) would start to lose it, and pretty soon we had what we called (back then, at that attraction) a "hostile takeover." Come prepared to wait. I wish it weren't like that, but...patience. (Also, lots of water and sunscreen.)
