My wife and I were first-time visitors to Sonoma. While I had a rental car, after I learned the size of the valley and the number of wineries I thought it best to leave the driving to the professionals. We had a wonderful day. visited four wineries, stopped for a tasty lunch, and at all times were guided and entertained by our driver, Paul. Highly recommend the tour for first-time visitors or those with only a day to spare.
