I'm coming to Vegas and staying at the Mirage. I hear that a lot of hot providers hang out and wait to be picked up. Is this true? If it is, do you have any opinions of this?

You'll normally find "ladies" at the bars of any of the major casino/hotels in Vegas on any given night. Prime time is usually 11PM - 3AM. Just have a seat and they will probably find you.

That said, the folks on this board will tell you to do the research and select one of the fine independents listed here. This way, you'll know who and what your getting, how much, etc. No surprises.
