My husband and I will be attending a conference in Monterey Aug 12-16. We have never been to Sonoma or Napa Valley. We are flying into San Jose and will take a rental car down to Monterrey. Can I get some recommendations on which place to go since we are driving from Monterrey are and then have to get back to San Jose for flying home? Any idea of time from Monterrey to one of the locations above? Thanks for any info/advice you can offer us.
