I'll be in the Naples area on the night of the 9th and during the day on the 10th. I am planning to spend the 10th in Pompeii and the Vesuvius area before heading off to Sorrento. l'm planning to skip the National Archeological Museum in Naples. It opens at 9AM and I feel like that's going to eat up too much of my time that I could spend in Pompeii and getting to the top of Vesuvius, though I'm open to suggestions if I can fit the museum in on that day.
However, I really want to eat pizza in Naples. I arrive too late at night on the 9th (11PM) so I don't plan on getting it on that day. If I don't go to the museum, then I plan on getting up early (before 8AM) and taking the circumvesuniana train to Pompeii. Are there any nice pizza take-out restaurants open that early in the morning?
If not, I suppose I could grab it on the way back on the 12th. I will be taking a ferry from Capri to Naples (probably the 4:30PM one) which would give me a 1.5-2hrs before my train at 7:20PM.
