DON'T FORGET THE SALAD CREAM.
My best tip is to leave plenty of space in your suitcase before you leave because gifts are so cheap to buy in turkey. Most foods are available but my wife will insist that we take the salad cream with us, not because she's mad its because you can't get the horrible muck there. Actually she is stark raving bonkers Ha Ha Ha". If you are traveling from England to turkey you will need a visa which you will be asked to purchase on arrival for ?10 pounds sterling,cash only. Bit of a con if you ask me. In the summer month's the heat can get unbearable with temp 45 degrees and over,so wear as little as poss. Comfortable walking shoes is a must as the heat is murder on your feet. Also a good pair of beach sandles or flip flops are essential as the sand will burn the soles off your feet. Actually while i'm on the subject, what do you call a Frenchman on the beach. FELLIEP FELLOP flipflop get it Ha Ha Ha. Anyway if you're booked on a Gulit cruise holiday there are no shoes allowed on board and don't bring any electrical items as there are no electricity sockets on board. A good medical kit is a must, treatment by a doctor or hospital in turkey is very expensive. As for toiletries like soap, toothpaist, ext, they are readily available and cheap Photography equipment including films are very expensive in turkey so make sure you bring enough to last. You will need some sort of swimming costume. Topless sunbathing in turkey is not allowed. Unless your a man Ha Ha Ha.
