Hi. I need a little help. I'm travelling from the Cinque Terre, renting a car in La Spezia and driving to San Gimignano for 3 days. I'm looking for the best location to drop off the car and hop on a train to Venice. Does it make sense to go to Siena (which is about a 20minute ride south) or is there a better option? I want to drop the car right at a train station. Any suggestions?
