If you don't know where to go, Park Royal Hotel is a no brainer.
Just go in and you will be surrounded by the freelancers.
But one thing I like is that they don't pester you; They will try to make eye contact with you and if you are agreeable, they will come over to your table.
There is also no need for ladies drinks.
Got a uni graduate aged 23 yeears old. Rate at 50usd over night. Not a great beauty, but made it up with youthful enthusiasm. Had 4 shots altogether, din know I still can managed that!
And I have to thanks bro Pearl...
