We are coming to visit family stationed at Ramstein AFB this December and wanted to take some time to explore the region. We will be bringing our 3 small children. While my husband and I normally prefer to "wander where the wind takes us" when traveling, with 3 small kids this won't be entirely possible. I feel like we need some semblance of an itinerary and then we'll leave each day fairly unstructured. We've had a few cities/locations suggested to us (Trier, Heidelburg, Stuttgart, Hohenzollern Castle, Neuschwanstein Castle, Rothenburg, and Nuremberg) and are wondering:
-which ones would you recommend for kids - they will have little patience for museums but they love to walk around - and which would you omit?
-how many days should we plan on if we are going at a slow pace?
-are we able to travel by train to all of these cities or will we need a car? I know we will need to arrange travel to the castles, but I'm curious about travel to the different cities.
We would love to hit Christmas markets along the way. Besides that, we just want to get lost in charming cities. Any advice you have would be GREATLY appreciated.
