An early start from Copenhagen to catch our train to Hamburg. 
With a large station like Copenhagen it takes a while to figure out which platform our train will leave from. 
We are staying in the same hotel as we did on our way up to Norway, therefore we knew where we were going when we got off the train which made it easier. 
We had arrived in Hamburg early afternoon which gave us an hour of daylight to have a look around which we didn’t have time to do last time.
