Thanks for the suggestions - yes, this looks like the right hotel, Non-NonRev, per their directions from OAK:

Take Hwy 880 North to Hwy 80 East (towards Sacramento) pass Berkely to Hwy 580 West across Richmond/San Rafael Bridge exit. Cross Richmond/San Rafael Bridge. Take immediate 2nd exit (Sir Francis Drake Blvd) follow Sir Francis Drake to stop light. Turn right at the stop light onto Larkspur Landing Circle. Hotel is on the right at 2500 Larkspur Landing Circle.
