I can offer some help once you have your plans more in place. I have been to Italy and Greece on a previous Med cruise and plan on going again this summer. I can help with information about how to get from the airport to the ship, train travel, how to get from several common ports to the main tourist attractions.
Let me know when you have something selected and I would be glad to help.
