DH and I have flights booked into Rome on 11/9 for 4 nights. We are spending 11/15-11/17 with our DD in Florence. We have 2 nights in the middle. I would love to see the coastline but can't figure out if we should go to Cinque Terre or somewhere along the Amalfi coast. We are not planning to rent a car and are relying on mass transit however, I am trying to avoid local trains and ferries to these areas as I believe their schedules decrease significantly after September. My daughter has recommended Positano but she is not very familiar with winter transit schedules, etc. What would you recommend?
