I am from UK and have travelled extensively in med, including a couple of cruises, if you post back your itinarary i would be happy to make some suggestions, we too prefer to be independant rather than take ships tours.
My husband and I, retired teachers are on our first Med cruise, Marseilles, Villefranche, Livorno, Cititavecchia, Naples and Barcelona. We find the shore excursion pkgs very expensive and we are wondering how we can do them on our own without worrying about missing the ship! Thank you in advance for any help. Jackie
You can easily do all of them by train with no problem. However I would suggest a shore excursion in Marseilles. The ship docks in a commercial port quite a distance from town. You can do a private tour with a taxi, but I have found availability somewhat scarce. But, that has just been my experience.
