I absolutely adore Interrailing and this is genuinely an awful thing to have to tweet - but it isn't worth the hassle and the arguing, eye rolling and growling from some of the nastiest staff I've ever met. Go anywhere else until they fix this.
So, I've been Interrailing in #Slovakia today. DO NOT do it with a mobile pass. The scanner that @ZSSK_official staff use claims that your pass is always invalid. They take this as fact and WILL argue with you in as rude a manner as they can muster. Stay well, well away.
Another mention in @RAIL of the station pub map that I helped to create a few months back. We're looking to create another in due course - as we know there are gaps! You can still download version one here: https://t.co/FGYp3I7EDg
