I went for two weeks last month, you would never know that anything was going on, it is a lot quieter than normal due to people being wary about it and cancelling.
I can honestly say that i feel safer walking round Turkey than i do in Manchester, i have been for the last 6 years and the people are fantastic, i have never felt any worry about going and love the place.
That said i can understand why people who haven't been before are not giving it a go after seeing everything in the media, to be fair i would be more worried about going to France rather than Turkey.
Turkey is a massive place and we stay around 400 miles away from Istanbul and the resort where we stay is around a mile inland and maybe 2 miles from the main strip, so the chances of being anywhere near any trouble are very very small.
