Agreed. Even when they build insanely complex ride systems like Forbidden Journey and Gringotts they manage to pull off insane hourly capacity numbers.
That said, I wonder how many awesome ride concepts have been dropped due to their insatiable quest for efficiency and riders per hour. I believe that is was killed the Iron Man attraction.
By the way... I did a quick calculation and Forbidden Journey alone cranks about as many riders per hour as BOTH Pandora attractions. That's pretty remarkable especially when you consider how intimate an experience FJ is with only 4 riders per bench. That ride is truly a marvel.
