We see a high speed train we would like to take to Naples for our day trip to Pompeii from Rome. I tried to book on trenitalia.com and also tried to call their booking number, but their credit card processing for US cards is acting up. Do you think it will be sold out by August 27th or will we be OK buying the tickets in Rome?
Also, how far is it to central Rome (hotel near the Borghese Gallery)from the airport by car? Thank you!
