I saw this post too late to post for ideas for your trip, but just had to put this in anyways for anyone else looking for this sort of thing.
A few years back, I spent a bit over a week at
this place in Healdsburg, CA. It was a really wonderful and relaxing experience. Our hosts there were top notch and very laid back folks. Breakfast every morning was superb. They helped us coordinate whatever activities we wanted in the days and evenings like getting us reservations for winery tours, restaurants, etc.. I ended up spending a lot of time just relaxing on a bench in the garden with a book.
When I got back, I was more relaxed than I can ever remember being in my life.
Damn it.... now I want to go back. Sigh.
