I was with a group of six fellow execs in Napa for a planning retreat. We used Perata Luxury Tours on two afternoons for some local winery tours/tasting. They recommended small boutique wineries and that is the way to go – only our group, very customized, great fun! Our driver, Dave Barber was friendly, knowledgeable and fun. He was basically ours for 2.5 days for the winery tours and to/from dinner in the excellent area restaurants. For small groups looking for a first class experience, go with Perata and ask for Dave!
