I would like to hear the answer to this as well. I spent awhile looking at availability at Andaz SD and found several dates where the "Unfortunately, this hotel is not accepting World of Hyatt points or award during those dates. Explore our other rates or modify your search." message appears. However, in every case I found, none of their "base rooms" (one queen or two doubles) were available for purchase (i.e. revenue stay) either. An example of Andaz SD offering rooms (base rooms or otherwise) for points but not for revenue would be very interesting (to me, at least).
