Elite status at a hotel might help. I've had lots of European Marriotts and Hiltons check me into a room when I arrived mid-morning. San Francisco hotels will be used to all sorts of odd-hours arrivals from Asia and elsewhere, so maybe this is possible there as well. Obviously pending availability. Even though hotels aren't full, many are more precisely measuring the number of hours a room is empty between guests as part of their COVID procedures, so that could limit things.
