I always kinda oped that the demolition might just be paving the way for something better. I loved the Adventurer's Club as much as everyone else, but the place was built to be one stop on a night of fun. Maybe Disney is going to build a newer Club that can stand more on it's own.
Disney might be kinda evil, but they're not completely stupid. If enough of us clamor for it back, they will take notice. And if it means profit, they'll most likely respond.
