Just wanted to give an update. I just left DLP and went to guest relations at WDS with a doctor's note of my condition. I asked for an Easy Access Card but she seemed like she was unfamiliar with it and gave me a Priority Access Card instead without an official disability certification. She was very sweet and everything was very easy but I am not sure if I was actually a candidate for the Priority AC as, again, I only had a doctor's note. So this situation may not apply for everyone.
