IMHO, this is a dumb promotion. Free admission is nice, but between the alination of SP holders since it doesn't matter to them and the killing of the family atmosphere at the gate, it just feels like a bad idea to me. And yes, I do realize that it's "Fright by Night", but that doesn't mean that the kiddies don't have their safe havens. Mommy and Daddy might not want Baby Junior to see Big Bad Billy munching down cockroaches at the gate.
And that doesn't get into the lost money in the deal.
