Anyway, I found the Venetian apt. info--The apartment was in Ca Cerchieri. My contact was Filippo Gaggia--he speaks English and is familar with the Bay Area because he attended Cal. The phone number I have for him is 011-39-3048-2648077. Wonderful experience.
I've been to Italy, well, 9 times if count the time I had just been in '99 in November and was checking flights to visit my sister who now lives in Nashville and found a $323 flight to Italy. So that March 2000, I zipped to Italy for 2 weeks on my own! Fab!
I have to say that the best advice I've seen here is to not cram too much into a first trip. Try the broad brush approach. For you who'll probably return, I see from your comments, you want a sampling of the style of life! Your folks may have different views of what they want to see, so I'd be sure you all talk it over.
Bologna is a good place to visit; interesting and somewhat leisurely; It has 3 nicknames--La Dotta (The Learned-from the oldest University); La Rossa (The Red both from its early communist leanings to its red colored portici) and La Grassa (The Fat! Have one meal and you'll get that one!). But in some ways, Bologna to me is a second tier or second visit city.
I may have missed it on the thread, but how long is your total trip? You said on the airline thread that you might fly into Milan/Bologna and out of Naples?
What I'd suggest Kicky, is that you and your folks sit down and decide exactly what you would kick yourselves for missing this trip.
But to "feel" a city, as Osso has suggested, you need to spend some time not doing anything but strolling, sitting and watching. I have kind of a questionnaire I created from helping people plan trips that might be helpful to you in terms of developing your ideas of what you want to see and do and where to do it! I'll post the important questions from it a little later.
The how to narrow things down part is the hardest thing. You don't want Italy to fly by, you want that
Dolce Vita, that
Dolce far niente
