Vegas Bachelor Party Advice Needed (and Hot Chick)

I am hoping the masses can help me with this one. I think we are all set with strip club recommendations, but I would like a couple bars/clubs to go to meet non-stripper chicks. Obviously the best case scenario would be to meet up with a bachelorette party or some group of girls like that. I have been to Vegas once before and had a good time, but I was disappointed in the amount of 20-something women I saw/interacted with. Obviously I was not at the right places because Vegas has to be full of 25 year old girls who are away from their boyfriends/husbands for a few days and want to [censored], right?

We will be arriving Friday afternoon and leaving Monday. Any help is appreciated.

Thanks
