To defend A2B - (this from their website & has always been the case ever since I started using them many years ago) - We cater for the majority of places within the specified resort/city; there are exceptions in Turkey, certain areas in the US, Canary Islands and Majorca. No shuttles are available to private addresses. Please contact us at admin@a2btransfers to confirm the address. If you don’t know the full address we can drop you off at the local tourist office.
A2B have always had this policy so it's not "from this week" although I appreciate you have now been told for the 1st time. The local agent in Fethiye is Diane Edwards (as you know) & she has agreed to help you sort your problem, it would have been nice for you to update this topic accordingly to give a fair balance.
A2B have always dropped me off at a private address, I just ask the driver & show him where to go, for the return I've always walked to the nearest hotel, is that really too much to ask for a transfer that costs a measly £6?
Just my 2p worth!
