rent a stroller you can carry stuff in there and He can take breaks when get tired. Get to the parks after 5pm its a secret that we (people who lived in Orlando) have by 5pm the sun is not as strong, the lines aren't too ugly and you would have the energy to stay for the fireworks at 9:00pm I always go to the parks with Tommy after 6pm. Shh dont tell anyone😄

My son had this issue when he was younger. We did custom orthodics for 3 yrs. It helped a lot.

Last time I got one of those scooter rentals when I had injured my leg and couldn't walk as much. Wouldn't have been possible to do Disney without it. Maybe try that?
