Couldn't agree more Laney. We've done the flights via Istanbul/Izmir and bus to
Marmaris and it couldn't be easier. We're doing it again next year. Travelling in Turkey is a dawdle, whether it's by plane, or bus, and so much cheaper. We've always found staff at airports and otogars very helpful. If you stand still for a few minutes someone will come and ask if you're ok, and point you in the right direction.
We got on a bus one day and the guy who comes round with the drinks and snacks remembered us from a trip we did 2 years before! We also keep in touch with one of the girls who had to find us accommodation when our flight home was cancelled due to snow. We saw her again at the airport on our way out to Kayseri 6 months later and she remembered us and got us straight through check in and told her friends on the plane to look after us. We were treated like royalty. She no longer works at the airport, but we're meeting up with her in Istanbul in a couple of weeks.
We're planning on a whistle stop tour of the area between Istanbul and
Icmeler next year, flying into Istanbul then staying a night or two in various places before catching a bus to the next place, and ending up in Icmeler, then a flight from
Dalaman to Istanbul connecting with a flight home with just an hours lay over. Piece of cake!
