A friend and I are going to stop in Pompeii for the day on our way back to Rome. In booking train tickets back to Rome, I used trenitalia to book Pompeii to Naples and Naples to Rome.
It is my understanding that (and please, correct me if I'm wrong) since I used trenitalia, we'll actually be leaving from a Pompeii train station about 20 minutes away from the site, not the Circumvesuviana station that's right there.
While it wouldn't be terrible to have to walk to the other station, I was hoping someone could give me some Circumvesuviana info. If I wanted to use Circumvesuviana to get to Naples, should I book in advance? Is that even possible? I tried going to their website but couldn't find an English version.
Any help would be greatly appreciated.
