I've spent a few nights at the Hyatt SFO. As
a Diamond you will get a room (if available)
on the top floor. The Club is closed. You
will also receive a voucher for a appetizer
and drink in the bar or Italian rest.. A
voucher will be given for breakfest which
may be used towards the price of any
breakfest. My last upgrade was into a full
on suite looking somewhat north towards bay
and SFO. The suite had a big screen tv w/
all the electronics and surround sound. In
addition to the standard room it had a living
room, dining table, bar w/ half kitchen and
half bathroom. Marble entry floors. Go for
this one. I don't remember the room number
but it is on the top floor. The room is not
marked with any puffy sign either. Make it
to the bar it has a good atmosphere.
