Stayed at Icmeler 3 times, was all set to buy there, but checked out Calis after going to a show and have bought a place in Calis. Like both areas a lot, night life better at Icmeler, Michael Jackson, belly dancers, break dancers etc etc at a lot of bars, (can get a bit much after a week, but good fun for a week)
Beach very nice, but very limited sun beds, as a lot of the beach is owed by Hotels and the public not allowed to there beach area.
Would recommend Icmeller for a one week holiday. Calis has more to offer overall.
