But one cast member, the senior facility coordinator, is essential to getting the job done.According to "One Day at Disney," the senior facility coordinator is responsible for purchasing every decoration in the parks. That includes larger-than-life Christmas tress, hundreds of ornaments, and tons of garland.It also takes a full year to get everything in order, though most of the heavy lifting begins in September when the decorations are removed from a giant warehouse. This is typically done at night when no guests are still in the parks, according to the book.Employees wear lots of hats on Castaway Cay, Disney's private island in the Bahamas.Sidney Bain, for example, is a Disney cast member featured prominently in "One Day at Disney."

She also has to trim and shape each area of foliage to "make them look beautiful."The exteriors of many Disney attractions are actually optical illusions created by a cast member.George Montano, the general lead of Disneyland's staff shop, is yet another cast member featuredin "One Day at Disney."
