I just don't buy the argument (maybe you're making it, maybe you're not) that Disney's queue management system is to blame. I think Disney Parks fans being insane is to blame. Whether it was FP, FP+, Genie+, or Standby only, people are so obsessed with the next new thing that I don't think we'd see wait times meaningfully improved with a "better" system.
I edited a little before you replied which might have made my point a little clearer but no, I don't think their queue management system is
entirely to blame although I
do think of it as being one ingredient in the soup.
But if Disney park fans being insane is
completely to blame, at which point in history did they lose their minds?
Pre-fastpass of any sort, the E-tickets all had big waits much of the time but most of the other stuff, usually didn't.
I don't remember there being much change there with paper fastpasses.
With FP+, suddenly almost everything had a fastpass queue including low-capacity attractions that frankly, have always seemed to struggle to handle that along with a standby line.
But I'm not saying that
alone is why - obviously, attendance went up in that same period, too.
I think the payment plan for FL resident APs rolling out had an impact, also.
To me it feels like a combination of lack of capacity expansion over decades, a queue management system and now a reservation system that attempts to make all things busy at all times
AND the rise of internet influences helping turn "FoMO" into a real problem in society rather than just something a few people take medication to handle...
I mean, there was a time when I'm sure they could have made an episode of
My Strange Addiction to document some of the fandom as it exists today but now, it's like that's perfectly normal.
I think all of it has fed into everything else and created a gordian knot of sorts.
It's a problem I don't know that Disney can find their way out of but it's one I feel strongly they could have avoided in the first place if they'd done things differently.
But that's from the guest perspective and maybe from the vantage point of an on-the-ground castmember. I'm still not convinced it's perceived as much of a problem for centralized management as long as they can keep raising margins.
