In addition to what John posted, I think Brad Smith (CCA Publicity Director) has some advertising going out during the lead-up to the convention via LVRJ. I don't recall specifics, so contact Brad if you need more info.

And of course, the big marquee at South Point always has a rotating splash advertising that's seen by everyone driving by on LV Blvd. or from the I-15 freeway.

And finally, the press releases that Brad generates for interested media to pick up are posted on the club website. A bunch of them are here:
