I agree that Hyatt's are typically pricier than Hilton or Marriott but they are also typically better hotels nad service. I n the same vein, I have the Luxury Collection of Sheraton to be pretty good although I am not convinced of the merits of Sheraton Club - Gold or otherwise.
Any comments on the Four Seasons/Regent chain and Ritz Carlton, particularly their resorts ? Why don't these guys have frequent stay programmes ?
