I am going to Marmaris at the end of the week and after spending two weeks in Marmaris I am going on to Hisaronu which is a little bit further on than Fethiye, we hire a private transfer and the cost is £65 for three adults, I have done this journey two years ago before and the cost then was £15 per person but I cannot find that cheap price again. The journey take just over two hours.
I booked this with transfers online.
