An excellent tour, very convenient, cheaper when booked off ship. Very funny and knowledgeable guide. Comfortable buses. Bring your jacket and be prepared to put it on and take it off repeatedly. Weather changes rapidly, and temperatures vary a lot depending on sun or shade. We were lucky and hit San Francisco on a beautiful day. Unfortunately, federal squabbling had shut down both Alcatraz and Muir Woods, but the city's lovely just to wander around in.
