AFAIK, Universal/Disney/Theme Parks give out free passes that are on a higher level than just express passes for free, as long as you pretend you have an illness.
I pretended to have strep throat one day at a Disney, got a pass for free, still not worth it though because park officals stare you down hard. I'd say pretend you have Autism (they count that), so just try your hardest to act like Suicidal.
