I brought this up in the Spirited Thread, but it belongs over here.
The TEA numbers, in addition to being guestimations, are extremely inflated fluffy numbers that look great for the companies. Just as they're one metric in part of a larger picture, they can also be extremely misleading. A lot of people look at those numbers and say "Wow, nearly 50 million people visited Disney World last year!" I've seen that even in news articles, suggesting each digit represents unique guests. As I mentioned in the other thread, the reality when it comes to unique guests is far, far different. One guest visiting the parks every day of a week long stay represents 7 first clicks in the TEA numbers. I think a more meaningful metric for attendance would be unique guests. What would that look like? Well, for WDW I would expect the number to look much closer to MK's total, say the 20-25 million mark (because yes, people do actually visit the other parks for 1 day). At Universal and SeaWorld, I would actually expect that number to be a decent bit below a single park's TEA number, due to the amount of APs at those parks.
Just something else to think about.
EDIT: And I should also mention that I think considering this, the gains in revenue shown by Universal are actually even more impressive. It suggests that their AP holders are actually spending a lot, considering the lower amount of unique guests, throwing a wrinkle into the theory that AP holders are stingy guests that can't really be profitable for the parks.
