I arrive into Napoli Centrale at 9.30 and would like to visit
Herculaneum on my way to my check in at Sorrento.
I see the Circumvensuviana Railway has a stop at Ercolano
[the stop for Herculaneum] on the way to Sorrento
Is there anywhere to leave my pack either at station or
the site itself ,visit the site then after that pick up my pack
and catch another train that continues on to Sorrento
