If you were to travel to one of these 3 cities, which one would you
choose and why?
- Augsburg
- Würzburg
- Regensburg

I am planning a 1-day trip from Munich via high-speed train and would
like to choose 1 beautiful city from the above 3. I already planned
trips to some other places in Germany including Rothenburg, that's why
I came up with the above list.

Many thanks!
