Rumors have been that disneys numbers are incorrect and have been that way for years. For example I had heard Tokyo Disneyland was higher than MK in 2014. Then this year both Tokyo parks were down? Then people always look at the large gap between Disneyland and DCA.Actually no, not if the goal is that relative ranking. For that to work you have to use the same methodology for all entries so you can't just cherry pick one set of numbers.
Now there are rumors that Disney somehow gets the numbers fudged. If true then the whole exercise is worthless.
