Disney App tracking would be the answer. They make the DAS selection in the app. If the phone's GPS goes into a standby queue area it cancels the DAS return time. They could get around this by leaving their phone somewhere, then going into a standby line without it. But I don't think a lot of people would do thatFrom hyperusers, no doubt. especially those who probably shouldn't have DAS as the right accommodation.
I do not believe the majority of DAS holders do this regardless.
Even if Disney heads want to do this...how to implement such a block? Noone polices the standby line. How about eating which are also the resting places for many? Some have proposed blocking that too. Curious on the how with this pie in the sky proposal...can it be done?
Enforcement of abuse is a much lower hanging fruit imho
