I have just heard about a new experience which is starting next month at AK. It is going to be based on Up and the wilderness explorers. You get a book when you enter the park (included in admission) There are 30 tasks around AK and you get a badge when you complete each one. Lots of other unofficial sites have news of it but cant find anything on disneyworld website or blog though. It sounds really good and something to keep people in AK a little longer.
