My advice is to take an English/ Italian phrase book/dictionary. Even if you don't understand someone or they don't understand you, each of you can use the book to point out what you are trying to say.
The Italians will love you for even trying to speak and they are most helpful!
I am envious. Have a great time!
Most hotels do not have washcloths so if you are used to having one, take it in a ziplok bag.
