And to me, this is where theme parks differ significantly from other entertainment venues such as sporting events, concerts, etc.
In those other venues, entering to experience the event is tangential to the actual event itself, i.e., once you're in, you're in. Waiting is not part of the actual "attraction" itself.
But that's not the case at a theme park - waiting in line is part of the fundamental nature of the goods (attractions) being offered. As such, forcing Disney (or any other theme park) to make alterations that fundamentally alter the "goods" being offered could well be seen (and was, in A.L. v. Disney) as being beyond the scope of ADA requirements.
Of course Disney should do all that they can to make attractions accessible for those with disabilities, but I don't believe that any court is going to force them to make accommodations to the point that it negatively impacts, on a consistent basis, the enjoyment of goods for those not using the accommodations, including those who purchase Genie+ (and the new iteration).
There has to be a balance, and until these changes, there wasn't.
