So here is the direct AVN convention website

Also I think everyone should attend the convention at least once.

If you want to hook up with a lady.
You should start trying to set up a date soon.
The ladies are usual busy with the convention etc.
Some may try to fit you in, if you plan ahead.

Yes

Please keep me in mind, when selecting someone to rendezvous with, as I reside in Las Vegas.

You may want to get into town early and try to set something up Tuesday or Wednesday, as the ladies are less likely to be busy with parties or exhausted from working the show floor.  If you try to set these meetings up now, you may convince the ladies to arrive early.

I went to the AVN last year

It was great, not sure i would go on a regular basis as the actual expo was a bit disappointing

In terms of booking porn stars to hobby with.

You can use agencies

BUT honestly, just talk to the girls, especially around the hotel and casino area outside (i even spoke to one at the airport on the way in) . Almost every girl i spoke to was up for meeting up and gave me her number. Trust me, the girls want to make extra cash. It would only be harder for the really big names like Nicole Aniston or August Ames  

Please don't listen to people who say you need to be industry connected blah blah blah and have all these special contacts to see these ladies. Just treat them as normal people, be respectful and ask politely if they do privates.

I actually found it easier to talk to girls around the hotel than at the parties where there were many more guys around and they were often with people they knew from the industry.

I definitely recommend staying at the Hard rock hotel for this en
