We are looking for a romantic place to have a wedding ceremony in Napa/Sonoma CA. Any suggestions?

Calistoga is 20 min north of Napa in the same valley, with alot more intimate lodging and close to wineries. For example http://www.christophersinn.com/ You can include not only wine tasting while you are in the valley, but there are bike rentals, spas, the most excellent restaurants in California. Napa Valley is only 30 miles long, and has more to do than Sonoma. For the best wine tasting experience try .http://www.kmalimo.com/ Knowledgable and can taylor a day around your expectations. Have fun and congratulations!

Why not go to Morton's Hot Springs Pool in Glen Ellen Saonoma Home of great spot you can do your own BBQ PICNIC AND HAVE FUN JUST THE SAME

while it might be difficult to find a place that will let you have the service in the vineyards (it is a farm with chemicals and tripping hazards and liability issues), i enjoyed a wedding at madrona manor in healdsburg:

Go to Barnes and Noble and ask them for this Magazine that has all the places in the bayarea and the prince ranges.. I think it's call something like "HEre come the ..."

Not sure if you have enough people, but here, try my favorite vineyard Chateau St. Jean, you owe me one :)
