The SF properties seem to be majorly impacted. I was supposed to be at the Marriott Oakland this weekend and arrived to very loud picket lines. Was told that there would be no services and I would rather not cross picket lines. They let me cancel with no penalty and I headed to the Grand Hyatt in San Francisco. I was on the 34th floor at the GH, and you could hear the picket line noise in my room with the window closed from the St Francis Westin nearby. I walked by the Marriott Marquis and they had quite a few strikers. Each picket line at the various properties I passed that had strikers was very loud. I would avoid Marriott SF/Oak properties that are affected until this is over.
