We are traveling from Keleti in Budapest to Wien Hauptbahnhof station by Railjet in a couple of weeks. I already purchased tickets through the OBB site including seat reservations in 1st class a while back. We are also planning to purchase the public transportation tickets for the Vienna city core area from Wiener Linien. My question concerns getting from the Wien Hauptbahnhof station to the Wien Mitte station which is walking distance to our hotel. I assume we would need to go to a ticket kiosk or window to purchase a ticket to get from one station to the other? I was thinking if we had the Vienna travel ticket we could use that but then I realized that is probably only for public transportation on subway, trams and buses within the Vienna core. Can someone clarify and tell me what would be best to do?
Also, can one purchase the 72 hour transportation tickets in any underground station once you get into Vienna (we would be exiting train at Wien Mitte as previously stated, checking into hotel and then we want to do the Ringstrasse tram to get our bearings).
Thank you so much, I have gotten myself a little confused!
