This tour was definitely worth it and I highly recommend it. I was in San Francisco for just 4 days for a meeting and the tour gave me a great historical overview of the city and ideas of places to check out solo when I come back (and I will come back thanks to this tour). Kimmy was the best, most energetic, fun, funny, and knowledgeable guide one could ask for and made the best of any minor hiccups along the way. I enjoyed the wineries that came with some key tips from Kimmy and the lunch stop was awesome too. I loved, loved, loved the tour!
