All good points.
Some of the solutions, even if they's re not as effective as DAS (especially regarding lower waiting times), from an accessibility standpoint, might work just fine. We just have to hope people won't abuse these as well
.
The sad part is that a good chunk of the lost business (which I don't think will be that large) will be people/families that actually have/deal with severe disabilities, where DAS might indeed be the only solution (and for those to whom this is true, they will know). Most others will still go and learn to use the other accommodations (which will yield varying results), and cheaters will either conform or find other accommodations to game.
Because in the end, WDW has no similar peers anywhere in the world.
Sure, there are other great parks, but people hardly plan family vacations JUST for that.
UNI Orlando has that crowd too but it's smaller.
Even Disneyland. I've been a couple of times and even though I love it, it doesn't feel the same going to Cali JUST to go to DL, as it feels going to Florida JUST to do WDW.
And Disney knows that.
And while that remains true, the elasticity of their demand will remain massive.
