We just had a one day stop, but had lunch at a winery, Checked out the monetary at the top of the mountain, and wandered around a couple towns. Mrs. Doomonyou Vetoed the donkey trip down to the Tender, so we took the Gondola. We'd love to go back and spend a week or so.
We had a one day stop, too, but it was one of the most beautiful islands I have seen.
