We arrive in Naples at 15:00, the plan is to do some sightseeing that evening and then see Pompeii, Herculaneum, and/or Mount Vesuvius the next day.
I saw on Tripadvisor lots of reviews for San Gregorio Armeno, I believe it's located near San Domenico Maggiore, but it didn't say much about it. It had a link to a website, but that didn't really tell me much either. Can anybody tell me more about it? Are the street vendors there everyday? Till what time? How can I visit the church? We plan on just taking our backpack suitcase with us, is it risky (should I rent a locker at the train station?)
Thank you all for your help.
