Not great value for money. The wineries we went to were completely different than the ones advertised (although still nice). $125pp to be driven to 3 wineries all fairly close together, and also a panera bread lunch box, seems a bit steep to me. The actual wine tastings were extra, and per winery.
There was also unclear communication about whether or not we were having a private tour. We were given a choice between a private tour for a 20% gratuity, or just join a bunch of other people on a larger bus. We chose the bus (thought it would be fun to meet new people, and no need for the extra $25 a head). However, I was called the day before and told we'd have a private bus still, but there'd be a convoy with other buses so we'd still get to socialise at each winery. This turned out to be false as on the day, it was just our group. At least I wasn't asked to tip 20%, although I'm not sure I should have offered (I am not from the US).
Overall, confusingly communicated and not good value for money. Our driver, Suzie, however was lovely.
