I'll be on that cruise and I think the ship will be moderately full, many cabin categories have booked up.
Here are the holiday events for both ships:
* A nearly three-deck-tall tree lighting ceremony in the atrium lobby, where "snow" magically falls
* A Christmas Eve visit from Santa Goofy, with surprises for kids enrolled in children's programming
* International holiday caroling by crew members from around the globe
* Special family time, when families join together to design and decorate their own gingerbread houses
* Classic holiday story time in the atrium hosted by favorite Disney Characters
* Traditional holiday feasts in Disney's three themed dining rooms
* Presentations of Santa Claus 2: The Mrs. Claus and Treasure Planet
* Multiple faith and non-denominational holiday services
* A ship-wide party to ring in 2003 and a New Year's Day tailgate party at ESPN Skybox and Promenade Lounge
