Re: Europe travel question
Another advice comes to mind: you can either choose nice weather, or English spoken. And in Germany you can't get either of the two :)
If you get tired of seeing buildings, streets and squares, you may want to spend some time in Provence (France) or Tuscany (Italy) or one of the very many other gorgeous parts of Europe. That will require a rental car, though, and driving may be a bit challenging compared to the US but you should be able to get an automatic even from smaller rental agencies if you book ahead with the likes of Hertz, Avis...
