Are you renting a wheelchair from home or from an offsite place? I would recommend that, then if he has a meltdown and you need to leave the park you can get to the monorail with him in the wheelchair. Then you can roll it right to your room.
Also is he able to understand a budget for toys and snacks? I would guess that would be a easy place for a lot of no's because there is stuff everywhere. You might be able to work on that ahead of time.
I think if you go at it as a trip for him and do what he wants you will both have a great time! When I was a kid I loved the monorail from TTC to Epcot! when our son was in a wheelchair the train was great, front row, just rolled him in. If he likes Pooh I would try that ride if he is okay with the dark and noise. You will have such a great time.
