You already have quite a few suggestions, still, adding some more as a few smaller Tuscan cities might be worth visiting as well. Volterra is famous for its alabaster, Carrara for its marble. And then there's the tiny community of Monteriggioni. It's a medieval town and when I was in Italy, ages ago, they had a medieval festival at least one night but I think it was more than that. With your food you got a clay bowl and clay jar and a carved, wooden spoon to eat with which we still have!
