What is your itinerary? You shouldn't miss David in Florence (blew me away and I didn't think it would) or the Leaning Tower of Pisa (another stop that I was ho hum about until I actually viewed it - wow!). If you contact someone like Access Italy and give them you arrival times, etc. they will suggest different tours. They will also give you contacts and/or set up tours outside Italy. We had a great guy in Barcelona through them too.
