Once again, San Francisco's most fabulous hotels have dedicated hours of labor and tons of candy to put together some truly spectacular gingerbread houses for your viewing pleasure, including a two-story maison atop Nob Hill and an elaborate sugar castle overlooking Union Square.

And don't worry about getting hungry as you drool over the sweet confections, some hotels are even sharing treats with you (and your four-legged friends)!
