A few days ago, I watched a travel show on PBS (not RSE) about Berlin, and now I want my next trip to include a few days in Berlin. We will be taking the train from Luxembourg. My husband and I love train travel and could do the 8 1/2 hour trip in a day, BUT, I am also thinking about a good place to stop along the way to break up the trip.
Any suggestions? I am anticipating a trip in September 2019.
