i agree wiith everyone here. i am an AP holder and we always have to present ID at the parking gate, so 'renting' out the AP is impossible.
As far as AAA, I'd contact your local AAA and get the passes directly from them. You'll avoid rip off on ebay from shady folks who may be lurking and you'll get a possibly discounted parking. I haven't checked on parking but I know my local AAA has slightly discounted park tickets and they are totally legit of course.
