I was in Sonoma 4 years ago and tried to book this tour but it was full & I went on Playpus Tour instead, which was great & I am still friendly with some people I met on it. But when I was going back to Sonoma this year, I was determined to try this tour and I am so glad that I did - it was the most fun. Riding a segway AND getting to try great wines - was just brilliant. And the guide was excellent - luckily there were only 2 of us on this particular trip (early Feb) - as I went with my cousin whom I hadn't seen for a while and Hunt was so patient with us as we had a family catch up over the wine tastings - the tour took much longer than scheduled due to our gossiping but we weren't rushed at all. And the segways are great, really easy to manoeuvre - you might find it a little bit tricky for about the first minute but then you get the feel for it and wonder how you thought it might be hard.
I also had to but another bag to take home as I bought so much wine..... Would thoroughly recommend this trip to everyone as get to try a bit of everything - wine, cheese, segway, see some nice Sonoma scenery at a relaxed pace.
