Mate,
Indeed, I've gone through the process. They won't even look at you if you talk about a 1 or 2 hour session. There is afixed group of English, Russian and Middle Easter women and the most beautiful ones. It seems like they are te finest apples that have been plucked.
Give it a try only if you want the high of picking up a lady from an exclusive location. The reason I'm saying this is because the service isn't any better than what you'll get from a good WG on AW (I haven't tried all the girls, been with thre I think)
One of the experiences though was absolutely amazing and I would pay a fortune for that experience....
