Hi- We are planning a trip in August with our two teens that has us traveling from Greve in Chianti to Positano. My plan was to drive and then return the rental car in Sorrento, then get a private transfer to Positano (and train back to Rome for the flight home afterward). But it seems conventional wisdom is to take a train to Naples or Sorrento. Thoughts on this? Where might be the best place to return the rental car if not Sorrento? Thank you!
