It's hard to say since we can't be sure about contruction during that time. My DS14 also has ASD and is a DISaholic.

We've gone every year except one since he was in Kindergarten! We've stayed at ASMo, AKL and WL. He enjoyed ASMo when he was younger, but now LOVES AKL and WL.

Also (please...no one jump all over me for this!) if you are comfortable mentioning to the CM when you book your room (and again a couple of days before check-in) that your child has Autism, you can ask *nicely* for a special request, such as "a quieter wing of the resort - away from construction if possible," or "a room close to the bus stop." We've found that the CMs are VERY helpful in trying to accomodate our requests, especially if we don't demand, but ask politely, and explain the reasons for our request.
Our first year at ASMo, we were all the way back in Lovebug, and each day my DS would have a meltodwon and kick up the flowerbed and scream alllllll the way back to our room.

The next year, when I mentioned his Autism, they offered a complimentary upgrade to a preferred building. It was years ago, but it was
huge help and made a world of difference.
At AKL and WL they have been great about room requests that we have sent in writing requesting rooms close to the bus stop, when we detailed how we sometimes need to make a break for it...and that can be hard to do with an overstimulated, out-of-control 14 year old!
Have a magical vacation!
