We're headed to Naples/Sorrento/Amalfi peninsula for 10 days. Our plans are to take in Pompeii/Herculaneum (or similar sites), the Archaeology museum in Naples, Sorrento, possibly a day trip to Capri, hike on the Amalfi peninsula. The list is not yet set! We will possibly stay most of the time in Sorrento rather than Naples. Travel dates are end of October/early November, 2017.
Most tours spend a week in this area. If we do that, we'd have 2-3 days to travel somewhere else before leaving from Naples. So, my question for the forum is what else might we consider that's near Naples and wouldn't require a lot of travel time to get there?
A couple of ideas that've come up - Matera, Caserta/Capua, Paestum
