Be aware that when the reservation info for the restaurant pops up, it still says something akin to "There are no characters at lunch." Fear not - WDW has made it very clear that beginning 12/4, Donald and the gang will be there.
Will this be a permanent character lunch? I hope so, Tusker House is the one must do character meal for us for our next trip. Also, it would be nice to do a character lunch at AK after spending a few hours in the park in the morning.
