Oh come on.... now your just using a straw man argument and being sarcastic. Have I heard of park closings? Yes I've heard of phases closings. They happen very infrequently.
The Park reservation system is daily, You are aware of that right? (See I can be sarcastic too)
.
Okay, putting little snarcastic snips aside.....
I think in general people understood that the park had a certain amount of capacity and on some very busy days it actually hit that capacity.
What's more frustrating now The amount of days they cannot get a reservation for the park they want to go to first.
If you have some data saying that the park reservation system is actually liked by a certain population, I'd love to see it.
In the meantime " I'm so glad Disney came up with the park reservation system, it really makes my park experience much better" is something I have yet to hear from anyone.
And just a double down, I'm not being sarcastic on that last part. I've literally heard no one ever say that.
Let's be honest here. It's not to fix the problem. As you stated. All it does is allow them to schedule a minimum amount of labor to attend to a fixed and predetermined population in the park. That's it and nothing more.
