That is my first stab at it. I'm trying to figure out how many days in each location. I think it's a good idea to do Salzburg as I have listed. We'll get a half day on the arrival day then two full days after for 2.5 days total. Then the dilemma is how many days in the Dolomites, Lake Como, and Lauterbrunnen? Two of those can get 3 full days and one of them can only have 2. So which location gets the short straw and only gets 2 days?
