On which note, they seem to be *much* better at crowd management and reducing queue lengths than eg. Disneyland Paris or the various UK theme parks. Queues are often much shorter than you might expect from the visitor numbers.
I don't have hard evidence of why this is, but I can't help but suspect that there's capitalist incentives at play here, and that the parks that have a fastpass system have every reason *not* to fix the queue congestion issues.
