As a diamond member, confused why I wasn't offered an upgrade or even the Hilton honors floor room. Weak buffet with great breakfast staff doesn't meet ok. Very aged property that management is obviously not maintaining well. Slow housekeeping staff with poor cleaning skills and aged room and mattresses. Will find better accommodations close in Emeryville. They Could make this single marina property a super star, but I'm thinking management and/or investors are clearly lacking in either resources or ability.
