Thanks for all the imput on my husbands Denver room. He tried again and the PP desk got more involved. They finally determined that the hotel HAD called Marriott and got permission to stop taking reservations under the guarantee for this period. The PP staff contacted the hotel and asked them to do whatever they could to find Traveler a room for the additonal night. The rep called him back today and said that it was not going to happen so he is going to get a room somewhere else for that night. We are thankful they really did try to help but still disappointed not to get the room. It's a little embarassing in front of clients!
