The overall experience was very good. There are 2000 wineries in the Napa/Sonoma area, and I found it overwhelming to choose where to go. The tour made the decision for you, and you don't need to call to schedule anything. I drink mostly $9-15 bottles of wine, so I'm not a wine snob at all, but I found 2 of the wineries to have less than average wine that I would never buy. Not only was the wine not very good, but Mayo Family Winery had an unappealing tasting area with no interesting buildings or anything to see. I also didn't like the Valley of the Moon Winery. I really like Buena Vista winery. The wine was excellent and had very neat buildings to see with a neat history. Larson Family Winery was decent wine and a nice outdoor tasting area, so I was happy with that. Overall, I debated on giving a 3/5 stars instead because I think they could have chosen much better wineries than the last 2, but because it was still a fun experience and because Paul was pretty cool, I give it a 4/5.
