Hello. I will be in Vienna for four days arriving on Thursday and intend to buy a 7day transit ticket for about 15 Euro which will cover my stay until Monday 9 AM. However, I read that you can travel from Vienna to Sopron using a special regional pass. Apparently, this pass allows you transit travel in Vienna and since Sopron is in the greater regional zone - you can use it to go to Sopron. When I leave Vienna my destination is Sopron for one night and then on to Budapest with a possible stop in Gyor. Can anyone clarify what this regional pass is and how I would obtain it. Thank you so much.
