Help Niki Cordell with their trip plan: Greece/Istanbul August 2013
Hi Niki! No need for a car in Istanbul, and it depends where you want to go in Greece. Transportation between cities is pretty easy. Have a great trip!
No, you don't need a car rental. You can rent a vespa. If you want to go out at night there are huge motorcoaches that pickup at all of the main points, They run till about 5am so no problem getting back to your hotel.
