After 3 days in Corniglia in late May, we have 6 days for Tuscany --(need to be in Milan late on day 7 to fly home.) We would like to see Lucca, San Gimignano, Florence and Siena. Thought it might make sense to go to Florence on day 6 and spend a night there before taking the train to Milan the next day. We don't want to race from place to place so what is the best place to set up base camp? We want a place we can take day trips from or simply relax if we choose not to do much else. We don't want to spend much time bucking crowds in Florence or elsewhere. Thinking of staying n a B&B within walking disctance to the center of San G. It sounds wonderful, but would it be better t to say in Siena or Lucca if we want to be able to go elsewhere?Would you choose Lucca over Siena to stay 3-4 days? If we must strike one of the places off the list which would you suggest? Is everywhere going to be mobbed in late May? THANKS
