From capsule hotels to pods in Japan, these hotel rooms forgo space for low prices and a once-in-a-lifetime sleeping experience. When there are two pairs of elbows in a tiny hotel room, someone’s going to get hurt. But a single traveler has more options, like New York’s two Pod Hotels in Midtown. Single rooms have a twin bed, flat-screen TV, and not much else, ideal for propelling you out on the town. In Tokyo’s Narita Airport or in Kyoto, the experience is more extreme: For less than $40, you can get a pod bed at 9 Hours (for, yes, nine hours, just long enough to rest and shower).
