We're driving from Heidelberg and plan to spend one night in Stuttgart because my husband wants to visit the Porsche Museum. Is it reasonable to try to drive to Tripsdrill first & spend some time there with our two girls (ages 6 & 8), and then visit the Porsche Museum in the afternoon? Or is that too much driving in one day to allow for both of those things? Alternatively, I thought we could maybe do Tripsdrill, and if we ran out of time, wake up in Stuttgart & visit the museum the first thing the next morning. Also, does the order of those visits make sense driving from Heidelberg (Tripsdrill THEN Stuttgart), or should it be the other way around? We're driving the following day to Rothenburg ob der Tauber. Thanks!
