I appreciate the reply and explanation; also your need for descresion. And as I mentioned, you owe no one any explanations, but since you did, some thoughts -
I think looks are such a subjective matter (your 10 could be my 4; and vice versa) - but I also think for a guy in residence for 10 years, you would already have better options. I also think "9's and 10's" often know it, and give poor service, but thats a topic for another discussion.
Think if you found a lady at Idem, for example and she went for under $70 - you would have felt you grossly overpaid in the past - (I get it BTW - the guy mentioned is providing multiple services to you - but you are paying dearly for those services - you never got their phone number/contact info - after a few times, you would not need this guy - just a thought).
You sound like a sharp guy who has made a few bucks - I would bet in business you would not tolerate a supplier making a 100% mark up on you. Just sayin'........
Another thing - if Hotel M has a party, or a function, you will find girls there - but unless things have changed a lot (they haven't) you will seldom just see girls hanging out there - the DelRey its not. (also don't discount the fact the M chicks often leave there - its not a huge place - and go to - yup, the DelRey - where they go for $80 - 100 - you don't have to pay what they ask the first time; its all negociable - especially as a local who could become a regular)
You are focused on the "model" thing, and if I pay a lot, I'll get a lot - in Vegas, maybe - in CR, not so much

.
The good news is by posting I suspect you will discover more options for far less $$$ - and for goodness sakes, if you find one you like, get her number - plus she is likely to have lots of friends who would love to meet you!
