Ok so I have never been but did a fair bit of research and found that:
There are 20+ clubs each with 5 to 20 girls, mainly from Eastern Europe and Africa. Big negative is that these girls are overworked. They have hourly meets followed by 'overnight' and 'day' programmes where they get booked by punters. That means the cute chicks are shagging up to 10 times a day every day for 6 months! There have been mixed reports around the quality of the girls and level of service you get. Based on this I have decided to postpone my trip and concentrate my efforts elsewhere
I punted one and when I asked how late she works she said 11pm then I asked what she does after she said sex party on a boat. They get fucked constantly.
Not sure how trafficked they are as I've seen some behave independently. I've seen some turn punters down when selected etc. But it wouldn't surprise me if some are made to work. I saw a bunch come to my hotel to use the pool. Didn't realise they were whores at first but the. Spotted their pimp keeping a close eye on them and then he proceeded to round them up after 45 mins or so. They looked happy enough. Again these may not be the typical trafficked ones.
The set up I witnessed was xxtl entry with a free drink. Girls dancing on stage. Choose one, let one of the 'waiters' know, meet her round by the apartments. On with the business. Pay the service charge of course! Somewhere around 200tl I think(close to 5 years ago!). 2 pops in an hour only.
Not sure which one I went to as I was taken by friends. It was a classy looking place. Main area was nice. Rooms were almost luxurious. I'd go back but I hear it's not as good as it was. However I also hear they have some absolute stunners over at the moment.
