Bed in a BoxWeary travelers, take heart. At China's Xi'an Xianyang Int'l Airport, climb right into a sleeping box and snooze away in peace and quiet. The snug little boxes, which sit right on airport hallways, have a floor space of roughly 32 sq. feet and a height of less than 9 feet (claustrophobs, beware). Bed, TV, reading lamp and wireless Internet included. Cost: just a shade under $5 for 30 minutes.
