I'm reading through the recent posts and it seems like it's more difficult to obtain a DAS for someone with a hidden disability. Will the cast members at guest services question the need? When we were last at WDW in May 2015, all I did was let them know my son (then 5) has ADHD, SPD and Anxiety and we had no issue getting one for my son. The pass made everything so much easier - my son could avoid anxiety triggers and enjoy his time in the parks. Is there anything else I need to do now?
