Very likely to miss a connection and get stranded in Stuttgart. Either:
- A. You're fine with risking it. You will likely be stranded in Stuttgart, go to the DB counter for a hotel voucher and travel the next day for free (no travel day needed).
- B. You wish to arrive in Paris that day. Leave Budapest 2 hours earlier and take the first Munich - Stuttgart train you see. Still aim for the 18:52 TGV.
- C. Travel to Vienna in the afternoon, have dinner there and take the Vienna - Paris night train (not daily). Book as soon as possible, very popular. 1 travel day needed.
- D. Take the Budapest - Stuttgart (or Zurich) night train and finish the journey next day. 2 travel days needed.
- E. Travel to Vienna in the afternoon, dinner there and take the Vienna - Bregenz night train: cheaper than the others and using brand new carriages. Next day travel via Zurich or Stuttgart. 2 travel days needed.
Feel free to ask anything.
