There's no way to know for sure, but my husband read the opposite. He read that they are slowly pulling back on SoCal specials (and specials in general, like at Costco). He read that they are trying to control crowds (over time) by eliminating these discounts and raising AP prices. That's why AP prices have raised so many more times recently than they have in the past. They're slowly using these tactics to find the limit of what people will pay and to get some of the cheaper ticket people to stop renewing their passes. He read that they consider the "payment option" as the perk for so-cal residents now, instead of a 2fer discount. I don't remember the article or blog that my husband read this on, but I can ask him when he gets home tonight and post it for you to read. There really is no way to know though until they make their move and either release it or not release it. Good luck - hopefully we're wrong and they get the discount out for your sister!
