We are planning a 6-day Tuscan trip with 6 adults from late October to early November, starting and ending in Bologna. Our list includes Bologna, Florence, Siena, Lucca, Pisa, Volterra, Montepulciano, Montalcino, San Gimignano, Chianti, Pienza, Val d'Orcia, Cortona, and Arezzo. However, we know we can't visit them all. Which ones do you think we absolutely must see, and which ones should we skip? (Florence isn't a must-see as everyone in our group has already visited it.)
