Lend me your ears! You night in Rome can get really exciting, fun as well as interesting. Well, actually it is not much you have to do, or something which will cost you an arm and a leg. A simple night-time drive is what I would suggest! May be you can go visiting a far away attraction in the evening, enjoy a great view and drive back to your hotel.

It is a real nice sight (something you will devour), to see the street lights reflecting against most of the ancient sites. Take it in!
