Hey Charlie, we are also on your cruise, leaving May 21st from Venice. My wife and I have already booked private tours in Rome, Florence and Athens. It's just my wife and I so we have room in all 3 cities if you have any interest. We are using Limoinrome for touring Rome, Spiros in Athens and sorry but can't remember who in Florence. Will have to check. If you have any interest email me and I can fill you in on details. Glad to hear you are on our ship. I know of about 10 other people who are on the cruise so far.
