If you want to rest your feet touring round the city without actually visiting any of the sights then this is a good tour for you. The tour takes too long travelling in one direction around Berlin that you waste time getting from one place to another, I wish I had bought the Berlin card and used the excellent hop on hop off trains instead.
This was the single most brilliant tour we have ever done. It was our first activity after arriving in Berlin and gave us a real feel for the city. We picked our Segways up from Fat Tire Bike Tours under the TV Tower - my wife and I and our 17 year old son have never ridden a Segway before. Our superb guide, Tom, gave us a quick practice on mastering the Segway and we all found that it was surprisingly easy. We then set off for 4 hours of sightseeing, pausing at various sights to be given information by Tom. He was excellent, telling you about all the many places we stopped at in a very funny yet knowledgeable way. We saw the usual sights but found many more which we may have missed had we walked round ourselves, for instance, Hitler's Bunker, the site of the Book Burning, a control post to name a few. We thought before we went that the tour was a bit pricey but it was actually worth every penny. I cannot recomend this tour highly enough.
