Hi, I was researching trains from Vienna to Budapest and the vast majority seem to be run by OBB, which I've heard of. That said, Regiojet is about half the price. Has anyone used Regiojet? I've only hear OBB referenced in this travel forum.
Also, OBB arrives in Keleti station whereas Regiojet arrives in Kelnfoeld. Is Keleti much more centrally located?
Thank you!
