One of the greatest things we did over the Christmas visit in 2005 was to go on the Yuletide Fantasy Tour. You can read all about the tour in details here is this review. http://allears.net/btp/tour_yt10.htm It was the first time I got to see the behind the scenes of Disney. You get to see how the people work in the design area as well as where they store the entire holiday decorations for all the parks. Our tour director was Carmen and she did a great job! Very informational and friendly. You also get to go the the Grand Floridian Resort shown above. Something to plan to do on your holiday visit to DisneyWorld!
Have a magical day!
