I usually go to Katranci beach at least once a year and yes, it's pretty well rammed with Turkish tourists. And echoing what KKOB says they not only bring along the kitchen sinks, they also bring along full sized fridge freezers and cookers etc...
Even if you can't get a lounger it's well worth a visit and make sure you take a walk past the water slide around to the other bay, nice view out to sea from there.
I've not been to Gunluklu, that's in the diary for this year
