We will be coming to Sorrento for a week in mid July and we intend going for a day to Rome. From my best knowledge the cheapest and fastest way is by train from Sorrento to Rome via Naples. If I���m not mistaken there are three train stations in Naples Centro Derizionale, Garibaldi and Porta Nolana- Corsa Garibaldi. Could someone tell me whether P.GA stands for Porta Nolana- Corsa Garibaldi. (got it from Treni Italia web-site time table) and do the trains stop in these stations? Are Napoli Centrale, Mergellina and Campi Flegrei also train stations?
One last question do you know if there are direct buses from Sorrento to Rome and vice-versa,is there a time table?
Thanks a lot for your help.
