Have you ever wanted a stranger dressed in a special all-in-one sleeper suit to warm up your hotel bed before you go to sleep? If you answered yes, Holiday Inns in London and Manchester have the perfect program for you. For a limited time, guests can receive a free, five-minute bed warming session from the hotel's human bed warmers. Holiday Inn spokeswoman Jane Bednall says it's ''like having a giant hot water bottle in your bed." Best job ever.
