Thanks so much for the kind words! And I don't disagree with the notion that a meaningful experience can be had without the Radius tour. Dachau is close to Munich, easy to find, and I suspect the guides at the site are excellent. To some extent I think it depends on your own pace at the time of the visit. We had just one non-travel day in Munich, arrived there as our last stop on a two-week journey through Europe, and it was SO nice to let someone else lead the way for the day, for one individual to handle transport details and the guided tour. Under different circumstances, we would have just gone ourselves, too. But for us, on this particular excursion, Radius was worth the price difference.
