I regularly go on familar holidays to Germany (Berlin, Munich, Trier, Moselle valley, Rhine valley) and they have been some of the best holidays ever. Even took the Miggy back home.
The German people are friendly, they generally like the english and they like beer and football too.
I even spent time living with German families on several teacher exchange programmes. Had a great time and really got to see their culture on a day-to-day basis.
I found that they are very sensitive about World War 2, Hitler, Nazis, concentration camps and the holocaust. They can't understand how the english are so preoccupied about the war. When they came over to England they were amazed about the amount of war films and documentaries on TV.
Also found they were even more sensitive about the re-unification of East/West Germany particularly the right wing element.
