Is the Mickey's Halloween Party significantly more crowded on a Friday?

Just wondered if anyone knew if a Monday or Wednesday night would be less crowded in anyone's experience

I would expect more locals to attend events on the weekends. I typically go on a Wednesday, but that has just been the way it fits into my plans.

For several years now every date has been sold out, regardless of whether it is a weekday or a weekend. Fridays and Halloween itself seem to sell out more quickly, sometimes as early as the beginning of August. So don't wait too long to make your decision.
