You must take a bus tour of Berlin when you arrive. It tells you where to go and what to see. Earphones with a variety of languages are available to hear the running commentary. As long as you keep your ticket, you can jump off anywhere on the route, see what you want and catch the next bus to continue on your trip.
Knowing this, you must catch the early bus and make a day of it. You learn so much and see sights which you may have missed had you been on foot. Don't forget to pick up your mapwhen you get your ticket. Some hotels sell the tickets in advance but since we were staying at the Westin Grand we only had to cross the road. (Unter den Linden)
Reasonably priced but make sure you don't miss the last bus !! We did !! read more
