Not sure why you would have to go and "meet some providers" when you can do a TER search and find any provider to your preferences honey :]

You could be picking up a ROB, an Upsell, a con artist, a psycho, a cop, or a MAN Baby!  LOL

You are in the perfect place to search for reputable well-reviewed ladies here in Vegas.
You do not want to waste your time at the bars,lounges,and casinos ladies in the hotels all that will happen you will encounter an upsell and end up disappointed!Also,don't bother with the cards passed out on the strip that is bait and switch and upsell.Stick with ladies that advertise here look on the las vegas ad board.Or if you find on another sites research that the ladies have reviews here or on another site.
There are many hot spots here to party and have a good time just not the right place to find providers.
Just my .02

....aren't my thing, I prefer well-reviewed indies.  Having said that, you certainly can find CGs in Vegas, possibly at a bargain, and there is very little risk of legal troubles.  If someone's going to get arrested, it's the girl, not the john.  And in most cases, even the girls don't get arrested -- they just get kicked off the property.

It's the quintessential Vegas option: do you take the sure thing, or do you gamble?  Many guys like the thrill of the hunt, like the spontaneity that goes with picking up a CG or a SW.

The video poker bars and penny slot machines in most casinos are a good start.  Look for girls sitting by themselves, generally near the elevators.  If she looks up at you and makes eye contact, she's probably a CG.  If she smiles and starts a conversation, she's definitely a CG.

The crosswalks across the Strip and the intersecting roads, particularly the MGM-NYNY-Excalibur-Tropicana conglomerate is also a good place to look.  Things start getting interesting around 10PM or so and generally continue to 3-4AM.  The later into the evening, the better the prices tend to get.  Weekends tend to be pricier than weekdays, slow nights cheaper than busy nights.  Supply and demand.

Think with your big head, know what you're willing to pay, negotiate before she comes to your room.  Most CGs will give you their number for later -- if you see someone you like, get her number, maybe you'll want to call her later that night or some other night.

Again, it's very different from the experience of hiring a quality indie, where you know what you're going to get and know what you're going to pay.  It's nearly identical to the streetwalker scene, but with much less risk of getting caught.  Many bartenders at casino bars also know the working girls, and might point them out to you if you ask (and tip) nicely.
