We are planning on renting a car in Chiusi and spending 5 days in the Tuscan countryside before returning the car and spending 3 days in Florence. Right now we have a place booked in Montepulciano for all 5 nights. The first 3 days we will spend around Montepulciano, Montalcino, Pienza and Siena. Then we want to spend a day in San Gimignano/Volterra and the last day in the Chianti region. Is it best to stay all 5 days in Montepulciano or should we spend the last 2 nights further north? I hate the idea of another hotel change but it would cut down on doing so much driving. Thoughts?
