If it does fall through I say Disney should take the money and actually make the beast kingdom or whatever it was called. I always am a little sad going to AK and seeing the Dragon on the sign but no dragons are in the park. I think a section dedicated to the fantasy of mystical creatures would be a better place to put your money long term than Avatar. Think about it dragons and such have been around for hundreds of year and still are as popular of a fantasy as ever.
I'm a little embarrassed to say as the Disney lover I am, I've never noticed the dragon on the sign. Guess I need to pay twice as much attention to the little things next time I'm there.
