I originally booked 3 days in Istanbul before my flight to India via Dubai, but realized after I hadn't factored in travel time. I changed my reservation in Istanbul to 2 nights, booked a night in Thessaloniki and thought I would be fine. Take the ferry to the mainland from Corfu, bus to Thessaloniki, and train the next day to Istanbul. Apparently due to Greece's financial troubles, that train has been suspended indefinitely from service. Now I have an extra night that I have to fill, another deposit I'll lose because I don't want to go to Thessaloniki anymore if I'm not taking the train, and I have to find a flight. I didn't fly in the first place because there are no direct flights from Corfu to Istanbul, so I have to connect in either Athens, Vienna or Stuttgart, making the trip minimum 4 hrs of flying.
In short, planning fail. But how could I know? I'm off to find a flight from Corfu instead, and see if Istanbul will give me back 3 nights. Ugh what a disaster...this is one time where I'm glad I'm traveling alone, because I'm pretty sure whoever I would travel with would want to shoot me right about now.
