It's tough trying to decide which way to travel in Turkey. I hear horror stories of Turkish drivers so I think I will limit my rental car experiences to areas outside of the major cities. I also have to avoid any mountain passes or scary high spaces - I do NOT do well in high places, and would freak out if I had to drive over a mountain road. Right now the best solution seems to be a combination of train, bus and car travel.
So here's my itinerary so far: fly out of Cincinnati on Thursday and arrive in Istanbul on Friday. Friday and Saturday will be spent on the main tourist attractions, and a Bosporus boat ride on Sunday. Sunday night I will take the overnight sleeper train to Ankara. It will save me from a long tedious daytime bus ride, and also saves the cost of a hotel room since I'll be traveling all night. I get into Ankara around 8:00 a.m. I'll probably spend the day tooling around there OR just take the bus for Goreme - haven't decided yet.
