It used to be that wheelchairs could not go through lines and needed an alternate entrance. Disney renovated most all the rides to allow for wheelchairs & ECVs to be accessible - those guests no longer needed an alternate entrance. No longer needed a return time.
When the GAC changed to a DAS, many guests lost their disability pass because their needs were being handled at each attraction based on their needs. They no longer needed the disability pass.……
……..When they first shifted to DAS, narrowing the scope of the use - my interpretation was that the DAS was now for those whose issues were triggered as a
direct result of being in the queue space. There are plenty of guests who have reasons why they would like the accommodation, especially since
Genie+ is now fee based, but Disney can offer a different accommodation.
