Tokyo's Mandarin Oriental hotel is trying to set a new world record price by offering the highest price ever for a hotel in a deal to commemorate its fifth anniversary.  The offer will allow use of the entire hotel, including its nine restaurants and all 178 rooms for $671,000 a night, each period going from three in the afternoon to noon the next day, and the hotel will apply for the record as soon as a night is booked at this price.  The catch?  You can only rent it on a day when there are no previous reservations.  Let me check my wallet.
