My boyfriend lives in Stuttgart in Germany and so far when I am visiting him I take the train from Paris where I live. However this is very pricey (> 120 € round trip) and I have to leave work early on Friday evenings to catch the last train which explains why I have missed it a couple of times.
It is pretty fast, however too expensive for visiting each other very often. I tried blablacar, it is much cheaper but there is not a lot of drivers offering the trip on Friday evenings when my weekend starts.
I was wondering if there was another way to get to Stuttgart from Paris that would be cheap and not take more than 6 hours.
