There was a posting awhile back on how to get from one area to another. We will be coming in from Naples and need to catch the Leonardo train which I believe is on platform 24. Can anyone help? Thx for now.
Do you mean changing trains at Rome Termini station for the Leonardo Express to the airport? If so, it's easy. Since it boards at the last platform in the main area of the station, turn left when you reach the end of your arrival platform and continue to the end of the platforms where you will turn left again to board the Leonardo Express. If you have a separate ticket for Termini to the airport, be sure to validate it before boarding.
