I've had just the opposite experience, by calling the hotel and speaking with the "Suite Desk" directly. I've always been given the lowest rate. But I also verify that the suite IS a suite and not just a larger room. SFO Airport Hyatt upgrade was to an enormous suite. They assured me they have no "fake" suites. Grand Hyatt Sa Francisco was also a nice sized suite with separate bedroom. Have never had a problem with availability either. This is one of the best awards Hyatt has, for those who need extra space.
