Flying into Amsterdam, but we really want to spend time in Germany! Looks like Westphalia and cities like Essen, Dusseldorf, Cologne, Koln, Bonn, etc. are very accessible and not overly long to get to!
Could you please help me? Are there fun and interesting sites and cities here for tweens (11 and 13) year old kids? Maybe a cool castle, chocolate factories, alpine coaster, you name it. we're open to it!
I really appreciate your insight, thank you for your time.
