I'm a little skeptical of some of Disney's numbers in the TEA report. Here's why.
There's an internal Disney document from 2010 that shows the number of days in 2009 that each park hit various attendance levels. Here's a remake of the chart:
View media item 3425 (I think lots of folks here have seen it.)
So, for example, the Magic Kingdom had 55 days in 2009 in which attendance was around 30,000 people. It had 16 days in which attendance was around 55,000 people.
If you do the math, it shows a MK attendance of around 14,180,000 when TEA reported 16,972,000. That's a pretty large gap. Its similar for Epcot, where the gap is about 1.2MM guests.
The MK numbers don't get much better even if you add in a couple of missing days at the highest attendance levels, and assume that the attendance is as large as it could be without being rounded into the next bucket:

The Epcot numbers are close enough in this scenario, though.
I'm having trouble reconciling these two sets of numbers with TEA's numbers.
