Check out City Vibe for Vegas to get some pro action, otherwise follow the advice about the strip casino bars at night for the indies. I go to Vegas 2,3,4 times a year, and let me tell you as mentioned above, I too like the Flamingo, but the LE was all over the place and I mean hassling the girls big time, as well as the security at the casino. Used to be the easiest to meet the indies, but not last time (end of April).
Other downers is EVERYTHING tends to be safe, and one SOG is the standard. You can bargain with them, and Ive got em as low as 250, but with anything hot you start at 400. And forget downtown all together. City Vibe online for the pro and try and find one that does incalls at her place if you have a car. Literally no chance to get caught by LE that way, but most of the girls deliberately live outside the city in Henderson or the like. Short drive, but worth it as you get better service, and safe as hell about LE.
I am going again next month, only will be at Harrahs this time as I didnt like the hassle I saw on the girls at the Flamingo. Getting caught by LE for involvement is expensive and embarrassing, and you wont get a break from LE for being a tourist. I prefer Caesars, but Im not into paying for the room when I get a GO room at Flamingo for Zilch. They are good, and ok for even a picky SP rendezvous.
Good luck, and check out the City Vibe and LVEscorts site, and take the incalls if you have a car. Closest way to get best service for near-TO prices. but we ARE spoiled here.
Anyways, good luck.
