Ohhhhh, I want to go to Italy again!! It's true, anywhere you go is going to be great.
If you have a car, and you like 'off the beaten path' places try Civita di Bagnoregio, north of Rome (on the way to Tuscany), it is an old cliff city, with only a footpath bridge to enter, the way they get supplies is with their donkey cart, it's an etherial place, and chunks of it are falling off as the cliff erodes. (it's not dangerous, though) You can find pictures on the web.
One piece of advice in Rome, when you want to eat, go down some side streets where ever you are, just off the main plazas and there is always a small family restaurant where the service is genuine and the atmosphere is fantastic, the pasta is always homemade, the prices are a little lower, you can't go wrong.
Whatever you do, have a great time and let us know what you did! (feed us who are not traveling
