Yes it's a real shame that Dalaman isnt open to Manchester/Midlands/Northern flights in the winter months but presumably the airlines don't think it's worthwhile as demand is low. However, for anyone who hasn't been to the Fethiye area in the winter, I can highly recommend it after seeing my first winter there. A completely different feel and it's so easy to get everywhere! You wouldn't believe how quiet the markets are and I never struggled to find a parking spot.
Mind you, as nice as The Harman Hotel was the first week we stayed before moving into our house, it would have benefitted from having the central heating actually switched on. The room warmed up a bit with air con heating on but the rest of the hotel was perishingly cold. And the hotel was full every night.
