Part of our trip will involve getting from Stuttgart to Frankfurt. I have heard that Heidelberg is on the way. Wondering whether it is worthwhile to hire a car to drive from Stuttgart to Frankfurt, is there other quaint little town along the way we can visit?
If we are going to hire a car, may be it is more economical to hire it for more then one day, is there other good scenic spots/ castles/ vineyards around Stuttgart that we can do as a driving day trip?
We have already planned to visit the Mercedes and Porsche museum but those are well serviced by public transport, right?
With me is my wife and an 8 yrs old kid, any suggestions would be most appreciated.
Thanks a lot in advance.
