Isn't it possible to make the reservation under your name and add an additional person, and that person would check in, and you would get the credit? Maybe a friend or family member would do it for you. If you did it publically you'd have to be very trusting that the person would not order a bunch of movies or damage the room. The Hilton in Parsippany, NJ is 55.20 GBP ai for checkin on 12/28. And I live near there
