Coming to LV this weekend for UFC fight.  Any recommendations or tips on best casinos or bars to find good providers?  

At one time or another all the strip hotels/casinos have gals roaming around. I have been going to Vegas since the 70s and seen working gals at most properties over the years. Paris and Bally's (probably more Paris) has been busy late at night the last few years. I've picked up .... ahh.... no.... I've been picked up at least six times in the area in the last ten years. About five years ago by a really hot lady cop. Got harassed but not much more. The cops of course tried to shame me, but my entire family is gone except for two sons who would have laughed and said way to go dad (which they did when I told them about it later).

My experience has been at the strip casinos and all have casino girls especially after 10pm.  The quality of casino girl is  commensurate with the quality of hotel you are staying at. I stay at Palazzo and there are always quality girls there and at the adjacent Venetian. However, as tempting and charming as they are. I have had some good experiences and bad experiences but never a great experience. Their prices often vary person to person and are not cheap. You are much better off to contact a provider on this site. Many quality girls are 'newbie friendly' and their prices and reviews are available here. I have heard of guys getting robbed by the girl and/or their 'business managers', plus the fear of undercover cops. Be careful.

rare to find a decent casino girl ..  i have gotten lucky once or twice but also burned twice and i wasnt even looking i got approached ... so otherwise i stick with TER / p411 or even whatsyourprice if you want to get adventurous    

Why gamble when you can find someone on TER that will not disappoint. I have done this 2 times about 10 years ago and never had a great time..

You might save some $$$ but it’s not worth it.  There have been countless stories of guys getting getting ripped off and robbed by these girls.  Just this year there have been multiple cases of casino girls that have been caught by the police for stealing expensive watches from their marks.  Picking up two girls at a time is even worse as one will distract you while the other will lift your valuables.  These casino girls are notorious for upsells as well.  Don’t even get me started on the hygiene and STD issues.  There is a reason most of these casino girls are trolling casino bars and the slot floors.   There are so many good, reputable and reliable providers here and on P411 that it doesn’t make sense to save a few bucks and put your safety or BCD time at risk.  

he sees them at RW the past two weekend night.

First it'll be a crowded in Vegas for fight night,plus guys acting the fools, girls coming from all over to"Work" and or "Scam" for the weekend, Oh yeah, I can see it? This is gonna end well.
But good luck

Best to flirt with Casino Girls and leave them in the casino .
They tend to talk a good game until you get in your room.
Four experiences over the years
One lame
One okay
One waste of time
One started out good, ended up drugged & robbed
