Disneyland & priority card..

Hi guys, going to disneyland in June. My 5 year old has recently been diagnosed with ADHD and still under assesment for Autism. The company we booked disney through said he would be entitled to a priority card, and i can apply online. On one of the thing thats i can send in, its a disability ID card.. now ive searched online and come across a few companiesthat do them, but dont want to be sending my sons info in, if disney dont accept rhat type of disability id card. Does anyone know what dissabled id card they do accept? Or does anyone know which website is a government Disabled Id card? Like which cards are done through the government and accepted? Has anyone been to disneyland and applied for a priority card for their child, and have any other ideas of what they will accept? My son is very fidgety, so cant zee him stabding in ques for very long (assuming the ques can be longer than a standard theme park) did anyone find the priority card useful? Thankyou
