Hello!
We will be on the cruise as well...and are busily planning all the port stops. We have booked tours in all but Rome (since we have been there and done most of the sights) and Villfranche. In Rome we plan on taking the cruise bus into town and doing it on our own. In Villefranche, we are still getting info. The last info was from a company highly recommended from many other cruises called Revelations. Their quote was high, but it was not per person, but simply by the van. 540 euros for a van that can take 6, perhaps 8 people. Their tours can be selected from a number of places...monte carlo, cannes, St. Paul de vence, Nice, Eze,. Too bad you can fit it all in!!
We are looking forward to this cruise, as you, and know it will be a special event to be remembered. Since this cruise is very port intensive, it almost requires you to develop a 'wish' list of sights...and then pare it down some due to the time restrictions. No matter what though, it will be a fabulous experience.
Nice meeting you :O) Happy cruising to us all!
