Disabled perks at universal studios?

My younger brother has autism, and most theme parks we go to have a pass where you can skip most of the line or all of it, Such as disney, the disabled/wheelchair pass. At this point my family is pretty spoiled about waiting, and he has it 10 times...

worse. We are thinking of going somewhere this summer and we all live in FL. My autistic brother loves shrek and popeye, so I was thinkig of going to islands of adventure/ universal studios, since we have never been there. But there is no point in going because it will turn out horrible if he is complaining the whole time about waiting. (He thinks that 10 minutes is a long time...)
Does anyone know if they have these, if we need to bring some medical papers to prove it (which we have) and how many people it can get through? (at disney it gets up to 6 people in with him)

Here is what I found:

convenient access for all our guests with disabilities. Many rides, shows, attractions, escalators and parking structures are designed to comfortably accommodate guests in a wheelchair or guests with other disabilities depending on their condition. There are designated guests-with-disabilities entrances for all our attractions in the park; don't hesitate to ask for more information.

At the Guest Services window, we provide detailed printed informational guides for persons with disabilities. Assistive listening devices and TDD phones for the hearing impaired are also provided at Guest Relations. Wheelchair and stroller rentals are available in the park for a $7 charge.
