AP Days Stuff
AP days is going on currently in its second week. They are giving out special AP Days buttons for pass holders along with recipe cards. Easiest place to pick up is the Paradise Pier Garden in California Adventure. In addition to this, if you have 4+ AP holders in the car when arriving you get free parking and a small AP button.
Hollywood Tower of Terror is doing a special Late Checkout theme where the ride will be conducted in complete darkness at night until it's final days in January when it closes for good. They also have special Late Checkout T-Shirts in the gift shop.
Trader Sam's at the Disneyland Hotel was selling special ceramic Tiki mugs themed after the haunted mansion ghost but they sold out (2500 made) on the first day because someone on the inside leaked the info on the release date and tons of people lined up for 2+ hours.

Update: Trader Sam's said that they will be restocking closer to Halloween so people can buy the Tiki Mugs again.
