Berlin details

For some reason, the sights in Berlin seemed to me to not be as quantifiable in how long I should spend there, so I just grouped them in rough chronological order in geographic regions. First day after the bus tour is west to east along Unter den Linden, from the Reichstag to Alexanderplatz. Second day is the stuff south of Unter den Linden like Checkpoint Charlie and the Jewish Museum, then the Museum Island stuff north. Third day is the west and central stuff like the Ku'damm and Victory Column. I think I've arranged it so that I have good areas for lunch and dinner/evening.
For reference, here's what I had in my original look at Berlin back in March.
