OK. So we are landing in Hamburg on 29.7.13 and then going up to Wacken on the Wednesday morning and staggering out on Sunday with the rest. So as someone who has never been to Germany, or Europe for that matter, would I be better suited you think going to Munich or Berlin for the next 3 days? I'd like to see the Berlin wall and that kind of stuff, but I'd also like to see traditional Bavarian type stuff too and the beer halls and all that. Plus a castle or something like that while I'm over. Any tips?
