We had an amazing tour driver! As newcomers to area with no experience, he was all encompassing of fun history bits, telling us about San Francisco, wineries, and tips for travelers.
All the wineries were good, we were very happy with the tour.
Only thing left to be desired was on time groups! One group on our bus was consistently late, but the camaraderie of the rest of the bus was hilarious as we waited for them to show up. Please, be mindful to be on the bus on time (or else those new Zealand ladies will use group shame, haha.)
