surprised that you haven't had any response on this, so thought that I would just"bump" it back to the top for you

i cant really say what you could do with 4 young children because they wont like sitting on a coach to get any were and they are not for the very young as there would be nothing for them to do there are boat trips but then again how would you cope with 4 little ones it would be a night mare for you ,.we go to turunc a LOT so go to see june at JM travel in the main street they have all the trips she might be able to advise you or go on there web site you can get the trips up to see if any thing is sutible it is

We had a nice trip to Akyaka last year with J&M Travel, with our family including grandchildren one aged 3 yrs and the other 8 months. It was laid on just for us, and they have 2 child seats, which you don't often get in Turkey. The beach is perfect for little ones at Akyaka.
My daughter also found the 3 year old loved going on the water-taxi to Icmeler, and the baby just slept in her buggy, again the beach is nice there for little ones for a change of scenery.
