The judge is spot on with their assessment. The system the mother was asking for is very similar to the old system Legoland used to use. I remember seeing how badly that was abused. On some of the lower capacity rides the disabled queue could get as long as the main queue. As a result the people with serious Autism couldn't actually ride as using a pass still involved queuing. Unsurprisingly when they brought in a fairer system (closer to what Disney use) they were slammed with complaints, mainly by people annoyed they'd closed the loophole.
