Heidy-ho!
Yes, hotel occupancy is factored into the crowd levels, along with daily and weekly park hours, and a couple other things. For November, I think it was when Disney posted actual daily and weekly park hours that provided the biggest part of the jump.
That being said, the crowd predictions we've been making seem to be about 10 minutes higher than what we're actually seeing, at least over the last two weeks. I don't yet have the hotel occupancy results from the last 14 days, so I don't know if that played into the lower waits. But I've asked our statistician to see if there's some other variable (like public school being in session) that we can check for influence. Any ideas on this would be greatly appreciated.
I don't see any huge differences in conventions, but I'll go back and check.
