we leave on the Carnival Freedon, July 21, 2008. this is our first european trip. we will be at thesve ports; enice, naples, cannes, livorno, barcelona, and dibrovnik. does anyone have recommendations for excursion for a family with a 12 year old? also, is it possible to just get off the ship and find companies with tours? which companies did you prebook? how about the ship tours? which ones are better priced? do you need to book a venice gondola ride in advance?
