You could take a day out of Strasbourg I think - one full day was enough for me (and it is a wondrous city but compact) and add a day to Salzburg to do a trip into the Austrian Lakes District just to the east - a k a The Sound of Music Country - by postal bus just over an hour to St Wolfgang - take boats on the idyllic lake or a steam train up a mountain, etc.

could be one of the nicer natural places on your whole trip

OTOH with another day in Strasbourg you could easily day trip by train or car to nearby Colmar and the Alscae wine region - Colmar is a cute town that makes a neat day out and with car you can putz along the Alsace Wine Road and hit a few wine houses and cute wine villages:

I hope you didn't drop Trier--it's my favorite German city. Yes, I am into Roman history, and there's plenty, but it is lovely. If so--well, another time!

My daughter and I went to Karlsruhe to rent bikes, and ended up staying one night coming and going. I'm not exactly sure what there is to see there, not that it is a terrible place. Based on what little I know I certainly would not plan four nights there.

I would say your time there is better spent elsewhere. And I agree with the others that Trier is worth the visit.
