I'm sure the AEE/AVN awards people will enjoy the lower room rates for staying in Vegas with the occupancy being down compared to the booked to the gills rates that occur around CES time.  Probably easier to get party house rentals away from CES time (Jan 10-13 this year), a popular option for those porn companies that wish to generate new content while in town.

Those that wish to pursue some extra income opportunities will always be around, either advertising here or other places that they will be available or going through some agency or hanging around the public areas like they always do.

As for being freer with the adult nature of the show, no casino property will risk their gaming license with any kind of open nudity or public lasciviousness, even in the expo or award show.  HRH has been nailed to the wall before the NV gaming commissioning for related issues to the nightclubs and pool parties that were run by third parties that didn't hoe the straight and narrow.  With new casino management installed this past year and getting the nightclub/rehab management people to clean up, they aren't going to risking losing their gaming license over some porn stars.  Of course, what happens away from public view...
