Wonderful tour! We really enjoyed being able to see and do so much in one day. Vince, our guide and driver, was excellent! Some of the wineries were a bit rushed, as it was difficult to get everyone back on time, but nonetheless, it was so much fun and worth it! We had about 1hr and 20 minutes at Muir Woods, then we headed to Mayo Family Winery, where we spent about 45minutes. We then proceeded to Sonoma Plaza for lunch (we did lunch on our own--only had 1 hour). After lunch, we went to Kieu Hoang Winery (this one was a short stop too, but such a beautiful winery). Lastly, we ended up in Cline Cellars, which was one of our favorites and the longest stop of all of the wineries. Overall, highly recommend it--especially if it's your first time going.
