We don't have much time and want to see more the lake and natural beauty. We went to south of France last year and loved the view there. So we are not planning to stay in Vienna. not sure if right or not.
Read some review and know that Hallstatt is a "must see". I am not sure if we should stay just one night or two. If two nights, we may probably stay just 3 nights in Salzburg. we plan to go grossglockner road and Heiligenblut for day trip.
I wish I have longer holiday. Love to hear your advice.
