As someone who actually lives in Vegas, I'd highly rec the independent scene, even though it's going to run you $300-$450/session. There's about 30-40 ladies , something for everyone, all ages, looks, service levels generally very good. PM me if you have queries about a specific lady. There are frequent (every 1-2 months ) meet and greets as well.
Storefront AMPs are invariably average looking Chinese ladies of a certain age who do hand releases for $100-$160, although I've heard some improvement on that front. I gave up on them some time ago. While the Northern NV brothels are acceptable, the ones in Pahrump, a 75 min drive from the Strip, aren't, IMHO. While there are many lookers, it's very pricey, and service levels marginal unacceptable. It might work for you if you have a lot of dough, want safe services only, and don't mind the fact that virtually all the ladies there will treat you like an ATM.
Stripper takeout is a possibility, the usual quote is $500, but it can be $300 with the right girl, or $1000 with a stunner. Depends primarily on if she'll play outside the club, and your game. Tough one for the tourists to crack, but it can be done.
That being said, I think the scene here is probably better and more cost effective, but not every Vegas visitor lives in Toronto.
The casino bar girls deal is really YMMV, most are pimped out and you never know who is going to rip you off in the room. But if you like the action that comes with that, be my guest.
