When I start conversations with SA ladies and let them know I venture to WinStar on a regular basis they almost always want to go with me. $ is different, but it's gonna cost you the hotel cost, nice dinner, maybe a show, and a couple $$ in gaming money. Then there is usually the rest of the costs.
I really think ladies from here are a much better value. FireKitten is one I know that is a good value. Eccie lady vs SA lady is you are paying them to leave instead of wondering what your going to do with them next.
BLM is correct on finding them in the casino is the best route if you can. Hasn't been my luck, but it would be best.
