Hey people, keep in mind that mishe has only one week of travel for Germany - and that includes Berlin - until she makes her way to Prague. That is very limited time.
IMO it just doesn't make much sense for her to go all the way down to Bavaria just to see Neuschwanstein or Dachau. There are many alternatives available to those who don't want to join the hordes of package tourists that drown Bavaria and the south in general.
Neuschwanstein is very beautiful (after all, 4000 people a day! can't possibly be wrong), but seeing the buildings in Dresden or Sansouci in Potsdam will more than compensate for that. Unlike Neuschwanstein, Sancoussi or Dresden Royal Palace are a real castles, ones that kings really lived in during their lives. Sancoussi is also very famous for its garden, a not-to-be-missed sight all in itself, especially in late May, early June.

For somebody based in Berlin, I would also always recommend going to Weimar instead of Dachau. Dachau got its fame because it is one of the few KZ (Concentration Camps) that is situated on West German soil. As such it was easily accessible to Western tourists based in Munich and like Neuschwanstein, gets recommended over and over. Buchenwald in Weimar however, was based in East Germany, and as such it has been open to the Western hemisphere since 1991, so many people not familar with Nazi Germany don't know it. Personally I find Buchenwald to be more interesting than Dachau, because 1) Buchenwald continued to be used as a Concentration Camp by the Russians and the East German Government well into the 60's and 2) because of its closeness to "the city of the Classic" Weimar. Not many people realise how important the Court of Weimar was to the developement of the German nation state, German thought and the course of German history. It is the contrast that makes it so stunning and grasp the true horror of what happened during the Nazi regime.
The same West Germany/East Germany thing also goes for the regions I mentioned - both Spreewald and Elbsandstein Mountains have been hidden behind the iron courtain for 40 years, so the majority of tourists there are still locals or Germans on a weekend away. And for those not wishing to go all the way to Heidelberg, Tuebingen or Rothenburg ob der Tauber, Quedlinburg is an equally great sight.
The key to travel in Germany is to make picks in the region you are in and see some things that are fairly typical for all of Germany as well as things that have some local flair.
So you want to see a castle? Choose a great one near you. You want to see a charming little city with those little wooden beam houses? Ask a local, there is bound to be one near you within a one-hour-drive. Sample local food? There is definitely a great German restaurant just around the corner. Mountains? Unless you are in the very north or want some very serious skiing, there is no need for the Alps.
If you go only to Bavaria, you miss out a lot of the treasures of the true Germany. For example the biggest German island, Ruegen, hasn't seen an American tourist in years, despite being (rightfully so) totally packed in summer. The Wattenmeer in the north where the sea shapes the land and the land shapes the sea, is very unique and exciting. Whole droves of German tourists and Maritime biologists flock to it every year. Yet hardly a Japanese tourist bus ever goes there. The Spreewald has seen some more group tourism, but only because it is close to Berlin and it is very easy for groups to rent a boat for a day. But it is virtually unknown to backpackers, despite the fact that it is a UNESCO world heritage area and that it is the home of the Sorbs or Wendish, who have their own language and culture, making it even more interesting. (Recommended reading for people going to the Spreewald: Any book by Jurij Brezan.)
Mishe, if you want to go to Ruegen (very easy from Berlin) I recommend that you camp on
Dorfstr. 5 d
Tel. 038302-9244 oder -53220
It is situated directly in the National Park Jasmund next to a bus stop. The camping lot is the end of a highly recommend and famous hike. You'll love it, I'm sure. Holler for me if you want to know more, I've been to Ruegen many times.
