I am there now and the prostitution scene is very much alive, just returned from the "Moscow" hotel and it was full of hookers, some OK, some stunning.
I must admit I felt a bit out of my league, the place was packed and I seemed to be the only English guy in the bar, this country has lots of rich people who have no problem paying the £18 entrance fee and £9 a pint, Dubai must be one of the only places left that allow smoking in bars, when I got back to my hotel I smelt like an ashtray.
I agree with you there, I could hardly describe it as totally discreet, almost all the upscale hotel bars are practically brothels. Just be very
wary, strictly no public affection in any form or then you could be in a spot of bother. Behind closed doors and they don't care, but holding hands and even hugging is a no go. For info on the best places to go to find a girl, just ask the taxi drivers! they often give the best advice!
If anybody is after a British lady, then try Chloe http://www.chloewindsor.com/about-me/
This is clearly somebody who isn't discreet about what she does. Very clear photos and she looks very nice indeed.
