pretty, I don't know anything about either of these, but here's what I found on the web -

AVN Event :
2009 AVN Awards
Event Date: 01/10/2009 - 01/10/2009
Location: Las Vegas, NV


internext event info :
Internext Las Vegas 2009 will be held January 12 -14, Monday - Wednesday, at the hip and luxurious Palms Casino Resort in Las Vegas, Nevada.

So I would think it would be possible, the AVN event is at Mandalay Bay.

Hope this helps.

On edit: Of course I hope it helps, duh!
