If they want to promote this new ride, IMHO they should experiment with a youtube-only ad. Adam the Woo, Kinsey, Draven (made up like Snow White of course), and friends -- any number of current, nearly, or formerly trespassed individuals file onto the ride. Once the ride starts, all heck breaks loose, lots of fast cuts, screaming on-ride, reacting to everything in a wild-eyed, "YEAH this rocks", gen-X rage. Speed metal music behind close-up reaction shots with weird lighting, making this out like a thrill ride or something dangerous. A "just kidding" reveal showing what they're seeing, the gem mine with Dwarfs animatronics, and that yes this is indeed a family friendly coaster. Everyone wearing Mickey ears w/ their names as they exit the ride, as if transformed by the experience. Ending caption "Spring 2014 - UN-trespass your way to the Magic".
No - of course that will NEVER, ever happen. Might amuse me, but maybe not the general public.
If we're lucky, we might get a 90 second super-ad premiering on Jimmy Kimmel and/or Disney Channel soon, then two chopped up 30 second ads and that feature different aspects of the super-ad. Families with perfect teeth, angular features, wearing pastel colors. A girl in a Snow White costume, a boy mouth agape as if to say "this is not a ride for princesses!". Snow White herself on the ride reacting to show scenes, hands on face saying "Oh". One of the Fab 5 on-ride with family going down the big outside drop. Family friendly, clean fun stuff.
