I will arrive at Atatürk airport at 21:15 on Saturday 7 September. I intend to reach my hotel in Kadiköy by a combination of metro to Zeytinburnu, then tram to Eminönü or Karaköy, then ferry to Kadiköy.
My concern is that there may be no ferries running by the time I reach the European centre of Istanbul.
Firstly, what time does the last ferry to Kadiköy depart?
Secondly, if I do not manage to make the last ferry, by what alternative means does one get cheaply from Eminönü or Karaköy to Kadiköy?
