I need to go from Schüttauplatz to Stadion (U2). I know the bus and subway routes but I will have to purchase individual tickets (I have a pass but it will expire by then). I guess it is €2,20 per head per journey. And we are 4 people. Is it more economical to just take a taxi (uber)? Which type of uber can accommodate big luggage (each of us is carrying one trolley and a backpack)?
