I'll be arriving tomorrow and staying exactly a week, ie returning on Tuesday next week. Is there some kind of a ticket valid for public transport for a whole week that can be bought directly at the airport and maybe used already to get into the city (and back)? Not sure if I will use it enough for it to make economical sense but I always like to have a ticket like that anyway to not need to buy single tickets and think about it at all during the trip.
Also, I do not have any Polish currency yet and my aim is to do the exchange in the city. That should be doable, right? Tickets and possible snacks etc at the airport - credit card, no problem?
