Considering this quote from the article; ‘Firefighter Aaron Clark, whose father was also a district firefighter, choked up as he recounted how growing up his dad took him to the parks using the passes and how he now does the same thing with his three daughters.’ I think you’re spot on. They also mention discounts in the park which was a part of a cast member badge. When I worked in the parks I could have sworn they also had the blue ID (as opposed to green for 3rd party vendor), but that was a while ago.
