I know this has probably been addressed, but I've read so many threads and haven't found exactly what I'm looking for that I'm getting confused, so please bear with me. 
We'll be having our first ever WDW trip this November. Our son, 5, has moderate autism.
I'm hoping to hear from some other parents of kiddos with autism about how they approached the GAC card. My understanding is that you have to inform the CM of the specific needs for your situation, is that correct?
I'd love to hear what specific needs some of the other parents have listed. I totally understand that every child's needs are unique, especially those with disabilities, but I'm having a hard time thinking of what exactly we need. At home, all the things we do 'differently' are just part of our normal daily routine, you know?
My hope, of course, is that he'll do fantastic and we won't even need any special treatment, but as this is a new experience for all of us, I want to have all my bases covered in case we do need some help.
I hope I'm making sense, and thanks so much to anyone who can help!

Our very first visit w/ my autistic son was a total disaster. We knew nothing about the GAC and were only just learning about his autism. I had to leave the first park at noon and just waited in our room for 8 hours until my oldest son and DH came back. I'll not even go into how depressing our
I really wish people would worry a little less about what others are doing and just enjoy themselves and butt out! 
I hear you.
We've finally gotten to that place too of just not caring, it's still annoying though.
ALL last winter he wouldn't wear a coat other than to go to school. We're in MN mind you!
You can imagine the looks we got.
No amount of trickery or coaxing or what-have-you worked. Thank heavens it was a mild winter.
Mine freaks out w/o his stroller. In it, he's happy. We'll be having him get out of it now to get measured for height and I know he's going to be "fun". I hope he eventually understands. We plan on doing the counting method where we count down from 3 so he knows his "solace" is coming back.
) My oldest son will be marching at DW with his high school band next spring break & I can't wait to go especially knowing that Disney is so good about granting the accomodations we need. It just removes a huge load of worry & stress.
