I will need to get from Rome to the port to take a cruise and i have no idea how to get from Rome to the cruise port. I have seen it is cheapest to take a train. Any idea on the cost and how long it takes and how do i get there? After the cruise i may go to Naples to see Pompeii, should i take a train to there also or is it close enough to take a cab? Or should i rent a car for Naples? I am thinking more on renting a car. I will be leaving Rome on the morning of may 6th which is the same day of my cruise which is at 5:30 pm, will i have enough time to get to the port if i take a train? How far is it from Rome to Civitavecchia ? Thanks for any help.
