Hello there, just out of curiosity, Bummel, have you decided yet ? Maybe you should post an idea of the route you visioned , so we can comment and add places or routes .I was born in Holland( which is a very nice country) ,but i live in Belgium for a long time now (which is nice too)
Since we all can access google-maps ,maybe i can give you a few nice places to visit.
Hopefully this thread doesn't mess up your ideas.
