I'm not an expert with Las Vegas, but the last time I went out to the Bunny Ranch and all the legal places, they quoted me prices starting at $700 for straight plain stuff. I said thank you, and walked out. They wouldn't talk prices until I picked a girl and went into her private room there. Not to mention, it's not exactly close to las vegas either. Plan on driving a while to get there.
I saw this post because I'm going to vegas this coming week and wanted to know the same info. I'm hoping it changed since 2009 but I doubt it. Probably just stick to the WSW and BP for entertainment, unless someone can enlighten me otherwise.
