Col, We had three days / nights staying in the lovely Dalyan in mid June. It may be busy now ( expected in late July August ) but those appealing riverside restaurants were all struggling big time when we were there. One establishment only had one table of customers throughout the whole of May:( !! No, Dalyan, like all the other Turkish resorts are reporting a downturn of Brit visitors this year.
Empty seats on planes from B,ham to Dalaman again reported even as recent as saturday 23rd July .
