Have just completed a trip in North Asia, and after completing my 25 Hyatt stays I canceled all further Hyatt reservations and changed them to Marriotts. I am SPG LT Plat, newly matched Marriott Plat. It seems to be true that Marriott have advised their hotels to treat 'new family members' exceptionally well. Upgraded to very nice suites, nice treatment, no problem with late checkout at 4pm....I know it won't last forever, but one more nail in my Hyatt coffin.
