@stefanlindbohm Super interesting result out of Railfinder.
Vidin - Budapest. Suggests to take the train in Craiova to Draganesti Olt, to catch the Night Train (which stops at Craiova).
Actually a nice idea. You get on the Night Train at a more civilised time.

Took some looking to notice this though.

Might have opted for that option too, except MAV (where you can get the interrail pass accepted) won't do Draganesti Olt only Craiova (CFR will, but not the Interrail). But then did realize getting on the train after 00:00 makes it a new Interrail day (and we travel much further after Budapest, and the first bit the day before is cheap) so maybe for good - even if getting on a train at 1 in the morning.

Bahn.de doesn't come up with anything so sensible... even if you route directly from Craiova it wants you to change trains at 2 or 3 in the night (urgh).
