I first used them due to the people we had been booked with passing us on to Fethiye Airport Transfers - I guess due to who's arriving when and who has a vehicle at the airport. I have to say the best we've used (and we've used loads) and as sadler says, among the cheapest (£65 return to Calis) and all newish Merc & VW minibuses.
We spent a few years doing the shared shuttle services and they were fine (esp. for me alone or when we came without the kids) but for the difference in price when it's 4 of us, I'm way to grumpy to wait on a bus for 20 minutes for some couple who stopped outside the terminal for a fag.
So I support those who supported us, I always have - and for airport transfers it has to be F.A.T.
