Trying to use these things is maddening. I see low-ish rates for the Los Angeles Ritz for both the standard and club level rooms on May 26 - 27. I'm being told all manner of things by every agent I speak to at Ritz, Marriott and Chase. One agent said their system is broken and can't process them any longer, another said they require a 2 night minimum stay, still another said to call Chase. I've emailed the GM at the property to enquire. Any other suggestions?
