Mickey Halloween Party or Disney After Hours?

We are debating Mickey Halloween Party on Friday, August 23 or Magic Kingdom After Hours on Thursday, August 22. Which event do you think would be less crowded? I also wonder why the Disney After Hours event is so much more expensive than the Halloween Party. Is that because they sell far less tickets?

Less crowded? Without a doubt- after hours. If you really enjoy parades, shows, character meets, and fireworks go to the party. If you want to go on as many attractions as possible- after hours.
