I was skeptical of these types of tourist trap tours but my wife took the initiative in booking this and I didn't so I went along and am very happy I did so! After going on the trolley, I don't know how else you would go see numerous vineyards on your own...maybe pay Uber or Lyft all day?? Sound expensive! Seriously nobody wants to go to all of these vineyards and watch what you drink because you have to drive. For $100 each, we got a driver for 6 hours, lunch from an excellent restaurant, met many new friends, and basically a guided tour. David, our guide was awesome and told us the history of everything and he his customer service was impeccable. My advice would be to do what you want by the 3rd or 4th stop. It may feel like you need to follow the group in to do a tasting, but nobody is forcing you to, so feel free just to shop, by a bottle and sit rather than join the group tasting.
