The ho's hang out in every hotel in Vegas. Sit alone in any bar, or even at a slot near a bar. 38 bucks is high, I am staying for 27/27/free/free at Bally's on my next trip.
This is why you have to do your research Whatever you do don't call the #s on the cards given out on the streets. You will definitely be disappointed there Be sure to check out the local review boards and you will do just fine.
