Update: First, thanks to those who PM'd me. I appreciate the help!
I called back with the code, spoke to two CM's and they wouldn't give it to me.
The first guy said it was available for my dates, put me on hold to check availablility and "crunch numbers" so he could give me a comparison of rack vs. the discount. I waited on hold for 10 minutes and then the line was disconnected.
I called back and got a different CM. This one really grilled me about the code, made me verify several things about myself, and then said it is a pin code only offered to selected households. I told her we've been to WDW a lot lately and I am an AP holder, so I'd like to know how to become eligible for offers like that. She said the marketing dept. handles it and this is a "highly specialized" offer that's "unlike anything we've ever done before."
Hmmm... Well, I pretty much knew they wouldn't divulge how to get a pin code - I think I just wanted to point out that as a frequent guest (as many of us are here) it would be nice to have an offer or two come our way.
Before hanging up, I asked the CM is there was any chance this code might be released to the public soon and she said no, it's definitely a pin code. Then she gave me the standard line about watching the website for special offers.
So, no luck for me. It's okay, because I had planned on getting a room-only, but what a great rate that would've been! And while I fully understand the reasoning behind the pin code offers, it's a bummer when they let some people apply it as a general code, while others must have the pin attached to their household.
