This tour was underwhelming. You spend equal time in the bus, and then just an hour at each stop. While an hour is plenty of time, there wasn't much to do at either spot besides sip their tastings. Both wineries were just off the roads, so there wasn't much to see or explore once you were there (there were no tours of the facilities). Although the price of the tour includes the tastings, if you're carless and coming from San Francisco, perhaps better to get a rideshare and split the cost between friends and then choose your preferred stops.
