My wife and I will be on a land/river cruise starting in Paris and ending in Zurich the end of April. We plan to rent a car and ramble around Bavaria for a week before driving to Theme Erding northeast of Munich. We will be there two days before flying back home. We are in our early 70's but are still quite active. We enjoy beautiful scenery, nice drives at a relaxed pace, comfortable places to stay and good food.
We have been to Munich several times, Neuschwanstein Castle twice, and have also visited Lucerne, Innsbruck and Salzburg. On this trip we plan to visit Ludwig's Hohenschwangau Castle, Oberammergau and Linderhof Castle, and Berchtesgaden.
We would appreciate getting advice on other places to go, lodging/restaurant recommendations, and scenic drive ideas.
Is a week too long in Bavaria? Should we consider including a trip on part of the Romantic Road (we've been to Rothenburg before), or to Baden-Baden?
Thanks in advance for your help.
