We will visit Vienna with a group of 11 students, arriving on a Thursday evening, and departing on Monday evening. Our accomodation is quite a bit outside the city center, so we are planning to use the mass transit system a lot. We will also use it to get to and from the airport on Thursday and Monday.
We are now deciding on our mass transit ticket options, as we are students and want to get the most out of our budget :-). We found out that Wiener Linien offers weekly passes, valid from Monday 12:00 until next Monday 09:00. In that case, we only have to buy separate tickets to get to the airport (which is in another ticket zone as well) on Monday.
The other option is to buy separate tickets on Thursday and Monday, and the 72-hrs tickets for Friday, Saturday and Sunday.
What surprises us is that the 72hrs tickets are slightly more expensive than the weekly passes, whereas we expected them to be cheaper, as the weekly passes are valid for more hours. Are there any extra restrictions for the weekly passes that make it less attractive than the 72hrs tickets that you know of? (Otherwise, I think the weekly passes are our best option)
