To be clear...I agree with
@21stamps about this...fastpass isn't gonna become a "premium" service. But from a different angle.
They do not have enough ride capacity now...let alone if attendance rises...to survive without it. Fastpass was a way to free up people for the gift shops...fastpass+ is simply a ride rationing system - born out of necessity.
Remember when they said That the bands would "revolutionize the experience and be interactive"? They dropped that pretense the next day...it's about you keeping your reservations. So while you don't have to wait 75 minutes for soarin...I bet statistically a lot use those useless ones you have to book for figment and nemo...
And then a lot of people move on to the showcase or out of the park after.
It's all about distribution...if people don't pay for it...now Then the park reputation will get blown out of the water like the French navy...
It has to be available for all tickets...lest they see how bad the situation really is. They have no more ride capacity now than they did in 2000...and If they get a push from what they're planning...it will be chaos without the computer balancing people.
