My elderly mother and I will be arriving at Munich on Friday afternoon (~ 2 pm) from Luzern and leaving for the states on Monday afternoon in early June. So we have two full days (Sat and Sun) to get around and my initial plan was to include a day trip to Neuschwanstein castle on Sunday. However, my mother said she would be more interested in Salzburg and I would like to change my plan accordingly (as long as my mother is happy, I am happy too). But my question to you, would it be better to visit Salzburg on Saturday instead of Sunday? I read some posts that Munich on Sunday can be very quiet but the same seems to be true for Salzburg. I also have to mention that my mother has some knee/back issues so our plans/activities have to be mild. My draft itinerary is below and I would very much appreciate any of your insightful advice. Thank you!
Friday PM: hotel check in and hang around garden/park in Munich
Saturday: Museums in Munich
Sunday: a day trip to Salzburg (can be on Saturday)
Monday AM: our flight is 4 pm (Munich airport) and we will stay at a hotel near the Munich station. So any activities in the morning?
