Madonna Inn - San Luis, Obispo, Calif.
The Madonna Inn is one of California's craziest landmarks, and that's saying something!
The hotel has 110 themed rooms that range from the comparatively low-key Time of Your Life room, which is swathed in the traditional colors of Mardi Gras, to the Caveman room, where everything is made from solid rock (expect the bed, of course) and features a private waterfall.
Of course, if you'd rather forgo purple, green and gold, and you aren't too keen on pretending to live in a cave, there are plenty of other options. There's a room made to look like a stagecoach, another one that resembles a canary cage and even a space that's designed to make you feel like you're sleeping in the clouds. You're sure to find a room at the Madonna Inn that has what you're looking for, as long as you don't mind swapping swank for extra kitsch.
