The whole thing is the brainchild of Randy Weiner, who produced "Sleep No More" and the venue The Box. It's a Game of Thrones-ish mashup of Mozart, dance, juggling, trapeze acts, acrobatics, whips, knife-throwing, and orgy... err... food orgy (there we go), all in celebration of "The Queen's daughter, Pamina".
Heads up: you may see people with a tiny jewel on them -- that's "the sign of The Queen", and it signifies that they've had a private show with a cast member in one of the small rooms hidden off of the main ballroom. For instance, they might lead you into a tiny freezer-like room and tell you that one spot on the performer's chest is a "stop" button, and another spot is a "go" button. Then, they'll put their hands high on your chest and lean forward until until you push "stop".
