We are a family of 4 (2 adults + 2 kids aged 11 & 13).
We will be in Vienna for the first time after visiting Munich and surrounding areas from Nuremberg, Wurzburg and down all the way to Fussen, Garmisch, and Mittenwald.
We would have also been to Berchtesgaden and spent days in Salzburg already.
Now in Vienna for 2 full days, what are the "must-Sees" and "Must-Do" activities and sightseeings with our kids?
Will we need a car for those 2 full days?
Please advise and many thanks for all your suggestions and feedback.
