We used Shuttle Direct to send our grown up daughter back to Dalaman. It worked fine. Cost was about £18 and we had to give the name of a hotel for pick up - they wouldn't accept Emir apartments for this (or any villa). We gave Nur Hotel as our nearest hotel & made sure we were early at the pick up. I think the pick up was about an hour earlier than we would usually expect, presumably in case there were others to collect. In our case, there was one other person already in the taxi & no further pick ups.
We were able to email the Shuttle Direct office to confirm the day before. Slightly more hassle than our usual super easy transfers with Enes but very useful for a single transfer.
