As a follow-up to a prior post I made recently, I am looking to book: Budapest to Vienna, then Vienna to Prague. Being that OBB website is temperamental to those trying to pay with an American credit card, would I be better off using the Bahn website to buy the tickets?
I noticed that the Bahn website does not let me pick specific seats, while the OBB website lets me pick specific seats for Budapest to Vienna, but not for Vienna to Budapest.
Any thoughts? The pros and cons of each website?
