I have booked a vacation to Italy for 3 weeks in October 2023. Traveling from Rome to Siena, then to Cinque Terre, then to Naples (then onto Amalfi Coast). Train schedule not yet available. Thinking the best is to travel by train. The longest of which would be from Cinque Terre to Naples. Any idea when schedule will be available and the length of the train from Cinque Terre to Naples (then to Amalfi Coast).
