We will be going to Italy and sailing the Adriatic for two weeks and I will have one suitcase and a backpack. As was mentioned one way to have a miserable trip is to have too much luggage and I've been guilty of that. Love the tips about palazzo pants and jersey clothing and rolling clothing to save room. We do not participate in formal nights and eat in the Lido or Windjammer in comfort which delights my husband no end. Remember, the dress code is only a suggestion and in the warmer climates people tend to be casual. I'm not much of a shopper so that simplifies things. Have a wonderful trip and enjoy the fabulous food in Italy.
