Bare, how exciting to cruise the Med in September. Make sure that you have black slacks, (the wrinkle free material) and you can wear different tops. Actually we've stopped dressing up on cruises to Europe and eat in the Buffet.
I know that Europe has gone over to a chip credit card so that can be difficult so it's best to have Euro's. Have you checked out your Roll Call on Cruisecritic.com? Many times people on your particular cruise will have private excursions that you can join. In the Med you can be locked out of ship excursions so best to make a reservation on line. Please let us know all about your trip when you return; I'm sure the doggies will be happy to welcome you home.
