I agree with you there. I actually floated a similar idea earlier in the thread. There are a lot of things Disney would have to do to change its operations such as adding capacity for people no longer standing around waiting in line by adding more shopping, more restaurants, perhaps large entertainment venues that could seat a lot of people (think: opening the Fantasmic theater during the day or putting something in during the day where the Rivers of Light used to show).
Cap the line to around a 30 minute wait in the physical line and everyone else gets called back when its their turn similar to how Tron and Cosmic Rewind work.
It could actually enhance safety as during an evac you'd have less people in line and you would need to offer less recovery passes if a ride went down.
Lightning Lane could still be used but more like Express Pass at Universal, charge a lot more and allow entry into the Lightning Lane whenever someone wanted to. It would ensure revenue from
Genie+ doesn't go away, it would just be coming from less guests.
It could potentially work for many current
DAS users as well although for situations where it doesn't you could still have a process for a DAS like option that used the lightning lane. In those scenarios it would also benefit the DAS user as the lightning lane wait should be significantly shorter.
Some rides that have a high ride capacity and generally low wait times like the People Mover could still use a normal standby queue instead of virtual queue maybe?
Its not a perfect idea, there are things Disney would need to do to make it all work - but it makes the most sense imho. Maybe long term Disney will eventually do that (probably test it at a smaller International park first).
