Your tour begins in Milan, Italy, and moves on to the pretty Italian Lake District and the attractive resort(胜地)of Stresa, your home for two nights.  Collette Vacations has carefully chosen the Costa Victoria as your home away from home for your 7-night journey along the waterways of the Mediterranean.  The cruise ship is filled with the warmth and culture of Italy and is richly designed with entertainment(娱乐)areas and very good living conditions.  It will take you to the places of your dreams.
