I first drove to Venice, then Rome and Vatican, and then drove to Florence. Then drove to Pisa en route to Monaco and Nice.

I do not plan on going to Venice again. Riding boats on sanitation water is not my idea of vacation. Florence is nice if you like old Castles or churches. I spent 2 days there. You can spend a week in Rome....lots to see. Vatican is must see. I would definitely do the beautiful drive to Pisa and Monaco. And Nice in France is a must visit again for me. Stay in Nice and go to casinos in Monaco during the day.
