"Has The Palms ever been considered as a site for upcoming CC>CC Conventions?"

Not that I know of. The conventions are normally booked a couple years in advance and 7,000 sq ft is not enough space for it. If I remember right there are only 3 or 4 hotels in LV with the amount of space that is needed for our convention.
Maybe Jim Steffener, Mike Skelton, or Wayne Thompson will see this.
