Totally agree there could be tweaks to a VQ system. Some type of timing window between your first ride and getting back in line, or a time restriction like after a certain time, or if a certain amount of VQ are available after a certain time, re-rides are allowed. I should also clarify that while i think VQ will be and should be the meta for rides, perhaps I should have clarified that as being your for your more popular/headliner type rides. What people stuck in the past here might call E ticket rides. I can see both the lack of need, and the benefits of having rides like small world/little mermaid/nemo, ect., rides with historically lower wait times not having a virtual que, both to save bandwidth and to give more things to do with the free time you're introducing with the VQ's. I agree it's a balance, and on whole I subjectively like the balance without waiting in lines, and objectively, like to maximize the chance of everyone being assured of the chance to ride a headliner once, even if that comes at the detriment to people who want to ride it multiple times.
As to your second point, i fully admit I don't go to, or care about any other parks than Disney. From the people i have talked with about Disney i don't think i have ever heard the complaint they ran out of things to do, unless they were at Disney against their will, and didn't really have an interest in the offerings to begin with.
The only points i think we disagree on is the 1) the arcade argument. Video games have almost totally transformed from arcade based entertainment to home and portable play. I don't think anyone would argue they enjoyed pay to play type scenarios, or aren't as engaged playing mario kart, zelda, ect., when they don't have to put quarters in.
the second disagreement is about never having themed ques. I don't know if we can play the hindsight game of going back in time and thinking about design theories based around tech that didn't exist back then. However It seems like the rides that WDW has chosen to use VQ with, Guardians, Rise, Tron each have pretty well developed themed pre-shows. Though to be fair, i can't say their design contemplated the use of VQ, or not. I don't think the VQ is going to take that incentive away, as your still going to want to manage throughput and capacity. A well themed pre-show allows you to have more people actively engaged in your ride, then just your loading/offloading capacity. I know personally i view my wait for a ride as being over once i enter the pre-show, so a well themed pre-show experience allows people to think their overall wait was shorter, AND that the overal ride experience was longer.
