We thought that, because today was a train day and we could, we would take the train right out to the end of the line, to a place called Ostbadsee Binz on Rügen Island. This was a lovely journey, across causeways and bridges, at one place with the sea on both sides. However, what we really would have liked to have seen - and I think we did see a bit, from the train, was the extraordinary resort barracks Hitler caused to have built at Prora, just down the line. Ostbadsee Binz looked as though the only really good thing was the beach, and it wasn't really beach weather, so we got on the train to Hamburg. Actually, the train was to go all the way to Stuttgart, but we were only going as far as Hamburg.
When we got here, we found the station full of very shouty people in fancy dress, which was rather disconcerting of it! So we put our luggage in a locker, and then caught a tourist bus to see the sights. Which were mostly water - lakes and canals and so on. After which, we were both hot and sleepy, so we went into a coffee shop and I had something called a frozen orange green tea, which seemed to be mostly orange juice with ice and mint; most refreshing. The SW had a milkshake.
We then walked down the main shopping drag - stopping for a pee at a random department store - to the Rathaus, and pottered around there for awhile, watching a boat come through the lock and so on. Then we walked up the lake or canal or whatever it was back to the station, and after a bit more pottering round the station, we had a very leisurely meal in a random restaurant, and are now sitting in the waiting-room on platform 14 waiting for the night train to Utrecht, which will probably be late!
