I am traveling to Berlin, Germany, on August 23rd. Does the cruise line transport people to the train station in Warnemunde (where the ship docks)? Is there enough time to see Berlin by the Hop on/off bus, especially if we are able to catch the first train at 8:05 am and arrive in Berlin by 11:30 am? Is there any scary moments on the train...like having only 7 minutes to get from one platform to another to make a train switch in Rostock? I'm a little worried about the time schedule in order to get back to the ship in plenty of time. The ship arrives at 6:30 am and departs at 11:00 pm. Any suggestions?
