Salzburg

Hi,

I’m in need of some suggestions for two days (three nights with the day of arrival) in Salzburg, Austria. I’m traveling with my parents (who are in their late 60’s) and the only must-do activity so far is the Sound of Music tour since my mother is a big fan. Other than that, I’m looking for suggestions on the attractions in Salzburg for the remaining time. I’ve done some searching and have one or two attractions in mind, including the Hohensalzburg fortress, Hellbrunn gardens and the Mirabell gardens. Anything else we should consider?

It has been a bit of a whirlwind in regards to what trip I am going to do this fall. I was originally planning on hitting just Croatia, but now my trip has been extended giving me enough time to do a real tour of Europe.

This is the path I was planning on taking. I am going to be there for about 4 weeks (maybe 5 weeks if I need to).

Quick overview:
Amsterdam (2 days)
Brugge (2 days)
Baden-Baden (1 or 2 days)
Munich (3 days)
Salzburg (1 day)
Venice (2 days)
Rome (2 days)
Florence (2 days)
Nice (or there abouts) (2 days)
