We did this tour in May and liked it enough to do it again! It is a great value for a 4 hour tour in an air conditioned bus. The tour guides are very fun and 100% fluent in English. There are 2 wineries (LA Cetto and La Casa de Dona Lupe)and you are given generous tastes at both in addition to cheese, bread, pizzas and jam tastings. You are also given a bottle of wine per attendee for free, but even though the wine is from the Valle de Guadalupe, it is not from either of the wineries you go to. We did not explore Ensenada since we ended up purchasing too much wine, but the tour bus will drop you off in town if you choose to explore.
