Here's the Christmas Tree and decorations at Disney's Animal Kingdom for the holidays. I've never been at this park at night, but I might try and go soon. It's very busy this time of year at the parks.
This video was filmed on Wednesday December 21st, 2011.
I created a store on Amazon.com with a lot of great theme park books and other great resources on theme parks. You can also find some of the music used in the parks there.
