A great hotel can be much more than a place to sleep. Around the world, some properties turn an ordinary getaway into an experience of their own, whether that means waking up to giraffes outside your window, spending the night in a room made of ice, or watching marine life swim overhead. From historic buildings with fascinating pasts to extraordinary designs in remote landscapes, these unique hotels offer a fresh way to explore the world. And in some cases, the hotel itself is reason enough to plan the trip.
