Play tourist. I like doing that sometimes. Plus kids like strange new places, right? I did, at least, but we traveled some, too.
It is a cultural thing, I think? I know it seems as strange to you as the Muggle world often does to me. It's unimaginable at times that it doesn't occur that you can just do that, you know? Just like... doing dishes the Muggle way is not my first thought. You just wave a wand to set the spells going.
So noted! Though Germany has the best beer and sausages. You'd probably be surprised.
