Yesterday saw one of the first large scale runs of Everest using cast from around WDW as riders for filming of the Discovery Channel specials, set to air around April 9, 2006. The reports from riders so far has been very very positive. The immense detail of the village area is receiving high acclaim, along with the smoothness, backward portions, and interior effects. Last but not least, some comments about the Yeti audio animatronic, "it BLEW ME AWAY!!! ", "the Yeti figure is without doubt the greatest AA I have ever seen", "you won't believe how fast that thing moves!".
One word of warning though, don't expect this attraction to be an intense coaster experience. Whilst it is thrilling, above Big Thunder Mountain and Space Mountain, and along the lines of Rock 'n' RollerCoaster, it is not a super fast, super high coaster. What makes this attraction so incredible, is the story, theming, effects, a great coaster ride system, and the way they are all integrated together. Disney wanted this attraction to be a major draw for Animal Kingdom and Walt Disney World as a whole, in the way that Splash Mountain is for MK, and Tower of Terror is for the Disney-MGM Studios. The design plan called for it to be rideable for the whole family, and that is exactly what WDI have delivered, and to great effect.
