This is a must do if you plan on heading to Napa and/or Sonoma. Not only did the discounts pay for the price of the pass and then some, the company also gave a us a proposed custom itinerary based on our interests and tastes. We did not follow the itinerary 100% but it was such a life saver in saving a tremendous amount of time in planning. And the wineries they recommended were almost all our favorites. It was only when we deviated from their recommendations that we ran into some disappointing tastings.
