Wilfried,

That sounds like a very plausible solution. That way it can be broken up by leg.

PS I used to live in Hamburg, and at the time was married to a German. We traveled to Amsterdam, and on a boat tour was able to understand whole sentences spoken in Dutch by the captain. But that was a long time ago, and it's been many year since "Ich habe Deutche gesprochen"
