My husband and I will be in Santiago for three days as part of our three week Chile/Argentina honeymoon. We are looking for the best way to spend one day on a Winery Tour on either the Saturday or Sunday (if anything is open on the Sunday?). We've been given a few very expensive options, and would love any suggestions on how to pack in the most experience for the best value. Can anyone suggest a good tour company? I've already booked a city tour through www.viator.com which seemed to be the best value for US$26 per person, but their winery tours are only Mon-Fri. I also read about the train tour, which doesn't seem like it covers enough ground. Any help or suggestions would be appreciated.
