AKL does have a Hidden Mickey Challenge - you can ask for it at the Concierge desk in the Lobby. If you visit AKL in the evening, before 9:30, night-vision goggles are available to view the Uzima Savanna.
At POR, fishing poles are available along with bait, for a fee, and you can attempt to catch and release fish.
Be sure to tour the new Art of Animation resort - great theming throughout and a nice food court too with gelato!
