Best place to holiday in turkey?

I am going away in september with my family ( 2 adults and 2 kids 21 and 18) and was wondering where the best destination would be to go? I have been to Bodrum with friends for the nightlife which was really good but not really a family holiday.Probably going to be staying in an all inclusive so won;t go out much although would like to go out for a couple of days and probably some good bars/restaurants! Helpppp!! :)|||I went to icmeler once for 2 weeks its quite nice|||Gumbet was a nice destination. Good selection of bars and restaurants but more family orientated than Bodrum.|||The best destination for a family vacation will be Istanbul. There are lots of all inclusive hotels, so there won;t be any problems with choosing one of them. As for the bars, there are plenty of them, you can try for example Tria Elegance restaurant, this is one of my favorites.
