I was hoping to get some feedback on a trip that my wife and two daughters, ages 12 and 11, will be taking at the end of August. We arrive into Vienna for 3 nights, then rent a car and drive to Salzburg for 2 nights. See Salzburg and Berchtesgaden area. Then drive to Garmisch-Partenkirchen for 3 nights, to do the Zugspitze, mild hiking, Oberammergau and Ludwig's castles. As of right now we end in Munich for 3 nights and fly out from there.
My question is that we have an extra night to play with. I was considering driving to Rothenburg o.d.T after Garmisch, and spending one night there, before driving back to Munich. Is this wise? Would I be better off just going to Munich for an extra night (which seems like too long in Munich with my daughters)? Or stay in Garmisch for one more night?
Any suggestions or other ideas would be greatly appreciated! I know I'm lucky to have the extra time to play with. Sometimes it's nice to just stay in one place a little longer, but I also want to expose my family to as much as possible while we're there!
Thanks in advance.
