Hop on a train at La Spezia and visit Cinqueterre towns Riomaggiore, Manarola, Corniglia, Vernazza, and Monterosso.
Rent a car and drive along the SR222 also known as "Chianti Road".
Make room in your busy schedule for a two-hour long meal at Osteria Le Logge in Siena.
Book a wine tasting tour at Castiglion del Bosco (their Brunello is my favorite).
Stop by "La Bottega del Sale" in San Gimignano and have a nice talk with photographer Duccio Nucci.
