"Should we stick to Napa, or include other areas?"

Well, Napa certainly has PLENTY of great Wineries to visit, but if you are looking for fun, and to cut loose a bit, I would concentrate on Sonoma and a couple of other areas.
Napa has gotten to the point where many people take themselves just a bit too seriously.
The guys in Sonoma are a Hoot. WAY Looser.
Some cool places down n Carneros as well. MacRostie is great.
Actually, in Napa, just at the edge of Carneros is one of my all time favorite producers, George Hendry. Amazing wines, great fellow. By appointment only.
Straddling the crest between Napa and Sonoma (they actually have two tasting rooms on top of the mountain, one in Napa & one in Sonoma, connected by a walkway - something about local regs!)is Pride Mountain. I've had no contact with these guys in several years, but everyone I have sent there has had a great time.
I'll mine my addled brain and come up with some others that are fun...
