Description snagged from the awesome mrstater:

It's like a virtual Advent calendar, where every day you open your browser window to LJ, you'll find a Disney-themed treat waiting for you. Whether you love the classic hand-drawn animated Disney musicals, the sleek Pixar films, or Disney's live-action flicks like Pirates of the Caribbean or TRON, there's a place for you to celebrate the kind of Christmas you'll only find in the Magic Kingdom!

Go forth and sign up! Whee!!
