OK sorry for the spelling for some of the hilltowns. Here's our plan. We're leaving Siena for Lucca by car. Along the way we thought of stopping the abovementioned towns. I'm wondering amongst the 3 which should we spend more time at? San G sounds like a tourist place which surprises me since it seemed so small and tucked away. How about the other two? they are sorta on the way as well. thanks!
