One thing my companions are considering doing is very Italian...a cooking class.
Oh, my wife and I did that while in Rome! It was awesome!
Well, we didn't do it in Rome, per se. We were taken out to a little village some distance outside Rome, in steep hills - you could still see the caves used as housing in Medieval times (and still used by artists in the summer) across the valley. We shopped for groceries in these *tiny* little stores in the village, and then retired to a small apartment for cooking.
We made several kinds of pasta, sauces, a chicken dish, bruschetta, and a fine tiramisu variant (which, given that I don't like coffee, is saying something).

The pasta (including ravioli, gnocchi, "strangled priests" aka strozzapreti, and fettuccine):
