Lately Halloween seems to the busiest time of year for a lot of parks. While the parks may be busy, it sounds like guests that are going are opting for off site more often. Which coincides with the discounts out there.
From what's being said from
Dreams Unlimited and others, Christmas and into spring isn't looking as good as now.
@clarker99 I do remember Disney saying they want lower attendance to help with guest satisfaction. IMO it's a big mistake if they truly go that route. By doing that they will end up pricing out a majority of families who make up their attendance right now. By pricing for those who can afford your product but have no interest in it will be a big failure. The people like those in Burbank look down on parks.
