I just had a thought...
I just noticed that I got the same email/pin tonight that I got on 11/7. But I passed that one up as the dates that were listed on the "Game On" email were for January 2012. And I was going in June 2012. But, tonight I noticed on the email it stated "Ask for other dates." So I went to this link that someone here on the message boards posted to see if the pin would work.

Sure enought, it did. I did get the 30% off my room for June 2012. So, what I'm trying to say, is even if you get a pin, you should check it out to see if it does work for your dates. Maybe everyone knows this, but I sure didn't.
