This trip was by far one of the best parts (if not the best part!) of our trip to San Francisco. 2 friends and I booked it as part of our girls trip and from the on time pick up to the perfect lunch (recommended by the driver, Paul.), to the wonderful lessons about wine making (made even more interesting by all the wine sampling), to the stop by Mrs. Doubtfire's house (from the movie), and an incredible view of the Golden Gate bridge, this was AMAZING. The driver was so incredibly knowledgeable and friendly he made the trip worthwhile. I don't think I've ever enjoyed a tour so much! Don't hesitate. It's worth every penny!!
PS. be prepared to pay $10 for entrance to Muir woods. I didn't realize that wasn't included so it was a tad suprising, but no big deal. All other entrance fees were paid.
