The elves also tend to the flying reindeer, which of course have a multi-level stable since they can fly, though I wouldn't want to have my pen on the ground floor.
And of course, if you were lucky enough to stay at the North Pole for a night, your fantastical room would be tended to by the elves. They really do like decorating for Christmas.
The last stop in the North Pole was the Globe Room, where Santa tracks the good/bad status of children. The globe is Bill Joyce's concept. I had the idea to put it in the center of a circular library of mezzanines that houses the "old school" book volumes of Santa's list.
