I didn't miss your point...I just totally disagree that not having Fast Pass would make it the same because the ride capacity doesn't change.
It doesn't create more ride capacity...I'm not arguing that. It still optimizes your time so you can ride 3 rides (plus more after the 3) at essentially any time you chose, in advance.
You can still wait in the regular line during EMH, early in the morning, during parades/fireworks, and at other strategic times. I don't think you can make a solid argument that the time you spend waiting in line is more with Fast Pass than without.
The reality is the parks ARE more crowded than they ever were. Look at the attendance. It goes up every year and the most recent report confirms attendance is at an all time high. Accordingly, if the parks seem more crowded, it's because they are and Disney has allowed a lot of areas to die, particularly at EPCOT and DHS, putting more pressure on MK.
Even with Fast Pass, especially at top rides, people still wait in the regular queue. Pull up the app right now and look at the wait times for Splash, Space, Thunder, Soarin', TSMM, and RnR. I don't agree that people have been pushed from the queues into the park. What you're seeing is the the increase in crowds and the effect of not having the parks fully operational.
Reality is a line for a ride with fastpass moves slower than one that doesn't have fastpass... The people in line that would have been out in 30 minutes are not out in 40... it doesn't increase the number of people in line I agree with that...
You can ride 3 rides at a predetermined time, yes... So the time that you would have been standing in line for those 3 rides is time spent somewhere else. Even if that time you would have spent in line for Thunder Mountain is spent in line somewhere else with no fastpass the result is you are now clogging a line somewhere else or clogging the park while you rush to or from your fastpass ride. You gained nothing from the fastpass beyond making the lines for non-fastpass rides longer and the regular lines for fastpass rides move slower... Nothing was gained beyond having you spend more time outside of the previous long fastpass rides regular line.
Now maybe its just me but the regular line queue for a fastpass ride usually offers more visually than the queue for non-fastpass rides... So maybe even if the net rides are even both ways, the fastpass put you in inferior queues for a longer amount of time.
