For day ops into Dalaman, going visual early made huge sense as it avoided the much more sporting circling approach. (for those who don't know it, main runway N-S, in a closed valley with mountains on W, N and E sides, open to the sea to S. Diurnal wind meant landing to N at night, full ILS, and to S in day, either visual straight in or ILS to 36 followed by circle to land).
The company encouraged early visuals, including an excellent guide of visual points to pick up, before you saw the threshold. As long as you could ensure continuous ground contact/VMC for terrain seperation and situational awareness, as per 737 J's post, it was by far the easiest way in.
