I am traveling on a 18 day Globus trip to Austria, Switzerland and the Oberammergau the end of May, beginning of June. (Vienna/ Salzberg, St. Moritz, Zermatt, Berne, Lucerne, Innsbruck, Oberammergau and Munich) I know Europe travel is fairly casual, I am having a hard time deciding what to pack for the different areas. I have noticed that the attire in many travel pictures is what I would call Snappy cashual. Has any one done a trip like this , and can anyone give me some suggestions? I am very excited and want to travel with one suitcase if possible. Thanks!
