Please give suggestions how to spend my last day in Italy for summer 2014. At the end of a week in Tuscany at a farmhouse north of Siena, we are spending two days in the Cinque Terre. I have one additional day to plan and then will be flying home from Rome the morning following the unplanned day. (I know that this is not optimal, but I could not pass up two frequent flyer award direct flights back home).
I have contemplated picking up a car in La Spezia and driving down the coast, staying overnight in some scenic town and then returning the car directly to the airport. Please give suggestions on a town to stay at or other alternatives.
