Almost magically, Walt Disney World Resort transforms into a holiday headquarters complete with millions of sparking lights, larger-than-life Christmas trees and miles of garland. From Dec. 1-25, guests will be able to take a behind the scenes peek at that magical transformation in Disney's Yuletide Fantasy, a 3-hour journey into the holiday history of Walt Disney World Resort.
Guests take guided tours to theme parks and resort hotels, learning stories about the themes of the Yuletide decorations and how Disney elves transform the parks and hotels into an annual winter wonderland. Disney's Yuletide Fantasy is open to ages 12 and older (guests under the age of 16 must be accompanied by an adult), and theme park admission is not required. The program is $45 per person, and class size is limited. For reservations, call 407-WDW-TOUR.
