That said, I had to beg to differ with your “attractions” section—no “must-sees”? Really?!? I mean, I know not everyone geeks out on this stuff like I do, but just to back up Jessica here, the National Archaeological Museum is one of the best archaeological museums in the world, with hundreds of ancient Roman frescoes, mosaics, sculptures, and much more, like the recently reopened “Gabinetto Segreto” of ancient erotic objects or the Farnese Bull, the single largest ancient sculpture ever found. Then there’s the Capodimonte, a little-visited art museum with some of the world’s most important masterpieces by artists including Artemisia Gentileschi, Brueghel, Botticelli, Caravaggio, Perugino, Pinturicchio, and Titian.

Those are just two of a number of major attractions. For more, you can see the post I wrote on Naples here: http://www.revealedrome.com/2011/01/naples-day-trip-rome-nuttier-southern-italy-napoli.html

One potential money-saver is the Campania ArteCard – there are different versions of it, but most will get you into two attractions for free (including Pompeii & Herculaneum, the most expensive ones) plus a whole bunch more at a discount, and most cover transportation (including the Circumvesuviana) as well. It’s a good bet that if you’ll be in the area for a few days (or more) & are planning to hit the major sights that you’ll save money with an ArteCard.

Also, I know it’s not free (only E6.50 last time I checked), but you neglected to mention the National Archaeological Museum, which is a stunner – it’s where most of the stuff they’ve dug up at Pompeii & Herculaneum is actually on display. I daresay Naples has that must-see attraction going for it, at least. 🙂

For future reference, here’s my list of free stuff to do in Naples (plus a few things that are cheap): http://www.italylogue.com/things-to-do/free-things-to-do-in-naples.html
