I’m just wondering if somebody could advise me on the easiest and cheapest way to get from Vienna HBF to Rathauspark (Austria Trend Hotel)- we are arriving from Brno via the Regiojet bus.
Easiest is tram D direct from the station to Rathausplatz/Burgtheater stop. €2.40 for a single journey or consider a pass.
Public transport is always cheapest, I think that is applicable to almost all cities in this world. I would follow Norman's advice to think about buying a transport pass.
Google Maps works great for navigating public transport in Vienna
Are you sure Treefinger? I am sure a few times people have complained on here that it wasn’t comprehensive.
For me it worked fine so far
I would preferably use the trip planner of the Vienna Transport Administration "Wiener Linien", because Google Maps often got it wrong in the past.
If they have improved the reliability of their trip planning tool on Google Maps, then it is certainly an advantage.
I find Google maps works ok if you know the city, but it often gives wrong or misleading information.
