It is my understanding that pooning in Vegas is expensive and pretty much a waste of time....all the flyers and cards that people hand out on the strip indicate a price....and that price is to have the gal come to your room....you have to pay that when she gets there and then negotiate a rate for her time and services...meaning if it costs you $40 for her just to show up and after she gets that $40 tells you that it will be $500 for an hour...you are going to feel like a jackass for calling her and forking over that $40 for her to stop by.
As for the brothels such as the Chicken Ranch....the way it works is you get buzzed in and take a seat at the bar and enjoy a drink and the gals approach you....maybe you buy them a drink maybe you dont....she tells you her rate and maybe you counter and maybe you dont.
As for CL in Vegas I have never checked it out as I dont like CL in general.....in Vegas the odds of getting a coked up SW seem pretty good IMO.
Your best bet....if you have the game.....is to pick up a gal who is looking for the same thing you are...Vegas is a party town....I have only been there once myself and it was with my wife.....I sure as hell got a lot of smiles from gals thrown my way....which was pretty nice but it sure made for a shitty vacation as my ex was such a paranoid control freeak biotch.
