I know you didn't. To me though when avatar is finished its a full day park.
Yes Animal Kingdom has underperformed. But look at Epcot and DHS thy aren't doing great either but still are in the top theme parks in the world.
People are too worried about rides. If you want rides go to a amusement park. This is a theme park, it's not meant to be all rides. Animal kingdom has two great shows, animal trails, will have a bunch of nighttime entertainment, dining has been expanded, merchandise has been expanded, etc.
