Is it easy to get a train from Romes airport to Sorrennto with a possible stop in Pompei??
Hi Janet -
There isn't any direct train from Fiumicino to Sorrento. There is one Trenitalia train at 09:38 AM that travels from the airport to Naples without any changes; from there you'd take a local Circumvesuviana commuter train (or private driver, or a transfer to the port from which you'd take a ferry) to Sorrento. Otherwise, you'd take a local train, such as the Leonardo Express, or shuttle bus into Roma Termini to catch a "Fast" train to Naples and then a commuter train, driver or ferry.
Here's a recent thread on the subject that might be helpful? :O)
