I doubt that this book is worth buying (but I admit I may be wrong). At least now you know that it exists. The description reads:

[Walt Disney World is known for its attention to detail. Never is it more evident than during the Christmas season. Each year brings changes around the parks and resorts. Take a photo journey with us that includes extinct guest favorites such as the Country Bear Christmas Special, an overnight visit to the Cinderella Castle Suite from Christmas week 2007, and a look around the Walt Disney World theme parks and resorts as you may see the decorations now. If you are heading to Walt Disney World for the holiday season, you'll enjoy using this book as a guide to finding decorations and displays! Over 300 color photos are included.]
