We were in Naples a couple of years ago. In February! It was lovely. Didn't get to Pompeii, because we had spent ten days in Rome and I overdrew my husband's patience by spending too much time looking at what he refers to as "rubble". Next time for sure.
This trip will be Pisa, Cortuna, Bologna and Lucca. Can't wait!
LOL! Your husband's "rubble" comment reminds me of my sister's visit to Rome. After three days in the city, he told her he was tired of "looking at all this old stuff."
Besides San Marino (which I think opted to remain independent, and never joined the Italian union), there are some other towns in Italy which have declared renewed independence. No one takes it too seriously, including those who live there. :') Here's one:

Skip Pisa ... its a dump and (leveled in WWII, town looks like Brooklyn with its 1950's style track apartments). Goto Florence instead, most beautiful city I have ever seen.
