I'm a Plat member and recently checked into the Palace on C+P.
1. Upgrade to grand deluxe room, but it was on Market St. and the work outside the window made it impossible to sleep, even though on the 7th floor.
Then moved to one bedroom suite (with two beds), quieter at night but then work on the building started at 7am. Checked out and decided to use points to stay at St. Regis Hotel on Missions St.
^2. As always treated well at the St. Regis and Platinum upgrade to Metropolitan Suite on high floor. Quiet, spacious, really wonderful. This hotel always provides nice upgrades, depending on availability.
