We're coming into Berlin by train in the afternoon, spending the night, and then leaving in the evening (on a night train to Paris). I haven't been since the Wall fell, and the rest of the family (wife and 11 year old) have never been. How can we make the most of this rushed and crazy visit? Any suggestions for centrally located, interesting but not too expensive hotels? (The Q caught my eye.) /Any suggestions for must-see places that we can manage in our limited time? Thanks!
