Greetings fellow tripadvisors, I'm hoping to get some positive postings regarding our trip plans for next summer. We are a family of four and will be flying into Munich at the end of July and staying for 3 1/2 weeks. Our 16 year old son is very interested in history. We opted to stay southwest of Munich on a lake rather than southeast as I would have preferred. We have visited Switzerland and Austria (although not Salzburg so do plan to visit there this trip) on other trips so we really wanted to focus our efforts on Germany. BTW, we will have a car. My husband loves driving in Europe rather than carrying my luggage up and down the stairs at the various train stations;-) After reading many posts on TA I'm wondering if we will find enough to do to keep us occupied for that length of time. Although we usually like one home base I am wondering if we should rethink our trip plans. Maybe we should move about Germany? We are not into theme parks. Any advise would be greatly appreciated!
