We will be doing most of our Istanbul sightseeing on foot. There is only one day that we will be using public transportation - a combination of the nostalgic tram, the funicular, and the IDO ferry from Karakoy to Kadikoy. and return. That would be a total of twelve jetons total, since there are two of us.
Are the same jetons used for all three types of public transport? Can we just buy twelve of them in the morning, so that we don't have to stand in line each time?
Thanks again for your help.
