<p>A third vote for Villagio. We were very happy with our stay there. Like others have said, it is within walking distance of several restaurants and a few very interesting shops.
We have also stayed at Meadowood which is absolutely beautiful. We visited friends who were staying at the Auberge resort and it was quite luxurious with a wonderful restaurant.
Our favorite vineyard was Silver Oak, but then it is one our favorite wines. We attended a reception at Far Niente, but I am not sure if it is open to the public on a regular basis. I second the recommendation for Domaine Chandon - if you can get a reservation for lunch it is divine!</p>
