My husband and I are planning to visit Tuscany on a trip in September 2014. For the majority of our time in Italy, we will be using the trains, however we're realizing that a rental car would be advantageous for touring the smaller towns. We were interested in possibly renting a car in Florence, and then taking a few days to drive through some of the smaller towns (Pienza,etc) and eventually continuing our drive to Sorrento or Naples, where we would then drop off the car. We live in Canada and are used to long drives My question is...if we rent in Florence, but return the car in the Sorrento/Naples, will we be hit with a big bill? I can't seem to find price quotes for different drop off locations online.
