I have read all the threads going back years and still am unsure. Everyone says take the train. It seems like a hassle to take a train from FCO to Termini and then another train to Naples then hire a drive to take your from Naples to our villa in Praiano.
We will have luggage and 4 people total. The villa has plenty of parking. I have no issues driving in Europe. The car hire is cheaper for the week (including fuel) then the trains and drivers etc. I will then have it should I want to use it when we are there for a week. If it sits parked for the week that is also fine.
What am I missing?
