at the Palms or most popular casinos.  Not necessarily from adult porn stars but you never know, there might be some up and coming starlet wandering around but unless you're a die hard fan of the adult industry, they'll probably be difficult to pick out on sight.

There's always plenty of unknown providers wandering around the casinos looking for clients.  They usually don't care for customer service so don't expect a GFE/PSE type session for several hundred bucks that you'll spend for the fun you seek.

Since you're looking now, you might get lucky if you contact some of the well reviewed providers in the database here and see if they have time and you pass their screening to book a session in advance and potentially have a much better time.  As AEE will probably bring more horny guys to town than usual, finding a good provider with time might be difficult.
