Hi, and welcome to the forum. You are in for a real treat and won't for one minute regret going to Icmeler.
The Turkish people absolutely adore children and will go out of their way to keep them amused. Your children will also love the Turks and it will be them, as well as you, that will be wanting to go back there every year

As far as the food goes, every restaurant has a kids menu, so you can't go wrong really.
Hope you have a great time.
Karen
