I voted as one of my friends.
I have an AP, I am DVC, I am TIW, I have the Disney Visa, I go to WDW multiple times per year, we have also booked 3 Disney cruises in the last 6 years - I have never received a PIN Code.
In 2008 a bunch of us went to WDW. I booked the rooms with my AP discount, and with my email. I had my friends name on the reservation as well.
He and his wife go to WDW every few years or so, maybe every 3 or 4. They buy no expiration park hoppers and save them (if that means anything). I get codes in his and her name sent to my email on a regular basis. As in Feburary, June, and October of this year alone.
