A little background- Myself, my hubby and another couple will going to Oktoberfest 2020 (Yeah, I know. I don't even drink beer) as the beginning of around a 4 week trip together. Hubby and I will have about a week in Budapest prior to meeting up with the friends in Munich and then time with my German family after we part from them. This will be my 6th trip to Germany. The friends have never been there. As this trip has developed I'm finding that many of the places that have been discussed involve going back to places I've been. I really would like to see some new places, and any place will be new for them. One of the friends is not fond of large cities.
I've seen much of Southern Bavaria, so I'm thinking somewhere a little further north could be interesting. We don't want to stay in Munich or anywhere so close that pricing will be affected by being there that time of year. We will have a car, but I want to take the train on the day we go to Munich for Oktoberfest. After our time in this area we will probably go on to the Innsbruck area, where we can then visit the Garmish-Partenkirchen & Mittenwald area. Any suggestions would be appreciated for a nice base to stay in for about 4 nights with day trip opportunities, and a reasonable train ride away from Munich? Thanks in advance for any advice.
