Whatever you want to call it... the standby queue gets jammed up. It's a scientific fact that the line moves significantly faster without the presence of a Fastpass line. We know this because we know how attractions ops works. I'm not sure if you're arguing semantics here or what, but the whole point is that the standby lines move significantly slower, and that's by design.
I didn't make any mention at all of the standby times. I simply mean that waiting in a 45 minute line that is constantly moving is much preferable to waiting in a 1 hour (or even a similar wait time of 45 minutes) line that remains static for long periods of time due to Fastpass. There are several reasons that FP+ inflates standby times. In addition to what has already been discussed, the FP+ systems has the effect of 'steering' park guests to particular FP queues when they look at their apps and see that it's one of the only attractions available at that time. They otherwise may have had no interest in riding that attraction, and the standby guests will have a longer wait now because of it. This typicall happens at your C/D ticket attractions. Now, I'm not saying that every guest does that, but the amount of guests who do is not insignificant.
Nobody here is saying that FP ruined their vacation. There are a fair amount of guests, including members of this board, who prefer the simplicity of having no fastpass queues for various reasons... that doesn't make us crazy or whiners, just like it doesn't make you crazy or wrong to prefer the FP+ system. For some of us, it allows our visits to be more spontaneous and less planned down to the minutae. For others, they enjoy being able to ride popular attractions without having to stand in a painfully slow standby line (much slower than it would be if there were no FP+ queue). I understand why you like it.. that's fine. For people who know how to take advantage of it and some who really know how to work the system, it can really work wonders... but I'd argue we've crossed a threshold of complexity here that's just too much. I sincerely feel bad for the first-time families who don't have hours and hours of time to dedicate to planning and research ahead of their Disney vacation.. so they get there and are a little bit screwed because they can't get the fastpass system to work to their advantage. Back in the day I would gladly volunteer to help family friends with planning their trip to Disney. These days I just throw my hands up and point them towards a Disney-specific
travel agent. I tell them DO NOT try to do this on your own.. let them deal with all the complexities and booking windows for you.
A good compromise for me would be to significantly limit the number of attractions which utilize FP+. Dumbo does not need a fastpass queue. Living with the Land does not need a fastpass queue. I could go on and on about that. Limit it to the headliners in each land.
