That's actually Small World decorated for Xmas.
The facade of SW at DL is much different than at WDW. At Christmastime, the entire exterior is covered in lights, and the dolls are dressed for the holidays. They also sing a combination of "Deck The Halls," and "It's A Small World" (there may be other carols in there, I don't remember).
It's really special riding SW at DL during the holidays!
