I am currently at the DT Mission Valley and actually can see the Hilton Mission Valley hotel in question from my window. I tried to book the Hilton but it was too pricey. I now understand why since it was booked by many $0.00 no-shows for fun and that procedure drove the yield management driven pricing system nutty. Big deal for some but a loss to this hotel. BTW many computer systems default to a "00" if problems occur in coding.
My best guess if the Hilton lawyers researched the 1728-ish written laws re "defrauding an innkeeper...." found posted in the closets, it probably would be an defraud-type offence in many states. Now the joker with his hostage-holding 300 booked rooms may have to explain to his 10th grade science teacher why he was not in class last week. He was in jail.
