Two 60-something's have a 15-hour stopover in Berlin on our way back to NYC from a cruise ending in Barcelona. Arrive TXL on Sunday, Dec. 1 at 8:30 p.m. and depart the following afternoon at 1:00 p.m. Never been to Berlin so we need some assistance in planning what to do/where to stay/how to get there. My thoughts are to see the Wall, Checkpoint Charlie and the Holocaust Memorial. Probably should stay somewhere near there unless there is another "must see" sight. Would appreciate any and all ideas. Also, what is weather like at that time of year?
