I think the event is at Resorts World now. Find a casino bar. Chat up anyone that looks interesting. Most of the higher end casinos on the strip should have interesting talent at the casino bars. The circular ones let you scout. At the very least, ask if they are attending the expo and where you can find them (this helps weed out the ones that work the casino bars all the time, generally poor service and lots of upselling).

While roaming the expo, there will be women promoting themselves working the hallways. Ask if they'll be available later.

Be aware that hotel elevators require a working key card to get to your floor.
