A near cousin to the Loch Ness Monster. Often reported as existing, never seen by most people, and the subject of much discussion.
Seriously, its a promotion code offered by Disney to some people on a completely unknown basis that permits the holder, and only the holder, to book their vacation at a significant discount. In my personal opinion, its Disney's random vacation subsidizer. Instead of a modest cut, say 10%, in rates across the board, they "gift" some people with a 30% or 40% discount, while the person in the next room will pay the full boat unless they are able to snag a
AAA rate or other such. Of course, because its the system that exists I now find myself equally ready as the next guy to sell my left kidney for a code.
Good Luck!
