If you have to choose between this and Charlottenburg in Berlin, choose this. We found it to be a nice place to see. Some of the rooms are pretty spectacular and you can see a few other buildings, palaces and gallery in the same park. The windmill was impressive and was running. We also made it over to the Orangery and you can walk up to the roof and see out over the park. It was a pretty nice day and the weather was fair. I found it surprising how flat the landscape is in the Potsdam/Berlin area. There is also a shopping district near by and some good places to eat. Make sure you get off the bus the stop before the train station in order to find the shopping district. We found it by chance. It's not such a big city busy area like Berlin. A slower pace.
