The regular ones, not the Premium. I checked on WDW's website, but they're no help. They just say (and I quote): "Special Passholder discounts and offers".
I'm wondering if the discounts would make it beneficial for me to buy an AP for our trip next January, while offsetting the cost of the AP itself. We'll be there for a week, and are planning on staying at the Caribbean Beach Resort, with the Dining Plan and Park Hopping added on.
