Asian Jackie....  cant go wrong.  Also Mars if you didnt get to see here when she was in LA.

Some criteria would have been helpful. By the way, I'm in L.A. but have had a few good experiences in Las Vegas. Actually we have Baylee LeFever in common. I had the pleasure of her company during one of her visits to LV. Anyway, despite a bit of a scheduling problem I'd give a thumbs up to Tori. A tad on the expensive side, sure, but I felt she was worth it. There was a website she was going thru (now defunct) at the time with a whole shitload of absolutely fabulous pix of Tori, close-ups and everything. It has been a few years, but based on her continuingly good reviews, I feel she's a good recommendation. I think I printed out a couple of the pix so If you're interested I'll dig'em out send them your way.
Still there are a number of really great providers in LV (per their numerous glowing reviews) and , as you have done your research, you'll have no trouble finding that special temporary someone.

Good luck.
