Here's the main things to consider:

1) The dancers make money via tips, mostly lap dances.  During the prime time (evenings to night), they make quite a bit.  During the off hours (from say 4am on to around 8pm), the quality and tips tends to drop off significantly.

2) No extras inside the club unless you like dropping a lot of money (over $1k, and that's just to get started).  Beside, a good lawyer will tell a dancer that got caught for solicitation that they need to take a 6 months vacation away from the Vegas GCs.  Depending on how much that means in tips, I don't think any dancer really wants to risk a long unpaid holiday.

3) Dancers are notorious for being flakey and late.  If you ever hear about the working of a GC, you know they have penalties for showing up late (increased house fees).  For the clubs, this is easy low hanging fruit.  So, if you manage to get someone to see you outside the clubs, don't pay them up front cause most of the time, they won't show up.  Just their nature.  Of course, if they have some kind of pressing financial obligation (rent, car payment/insurance, etc), that always works to your favor.

Cost wise, you're looking at $500+/pop.  I'd rather take an hour with someone like Jenni or Nikki Avalon at those prices.
