Assuming the dates are correct http://www.wdwinfo.com/holidays/halloween.htm (yes, I know there was a small debate on that)
At first thought, it seems reasonable to think that Sunday, Oct. 23, might be busier than either the following Tuesday or Thursday.
On the other hand, do they all sell out that close to Halloween? So perhaps it really doesn't matter?
