Welcome to the Disney Parks Moms Panel Selha ~
I have a son with Cerebral Palsy who uses a stroller as a wheelchair. When you arrive at the first theme park during your visit, go to Guest Relations and request a band that will indicate to Cast Members that you will be using the stroller as a wheelchair. They will date the band so that you can use it during your stay and you will not have to go back to request another one. Be sure to put it on a handle so that is clearly visible for Cast Members.
Here is some
information regarding attractions for Guests with Mobility Disabilities including those that allow Guests to remain in their wheelchairs or ECVs, those that require Guests in ECVs to transfer to wheelchairs to board and those that require Guests to be mobile to enjoy.
A lot of the queues at Disney are now mainstreamed to accommodate Guests traveling in wheelchairs or EVCs. If there are queues that require Guests in wheelchairs to enter through alternate queues, you can see a Cast Member for assistance. They will give you a return time to come back to the attraction based on the current wait time. There aren't many of these and most of them are found at Magic Kingdom like the Tomorrowland Speedway or Star Tours at Disney's Hollywood Studios.
Please feel free to visit with all of your planning questions. Its my pleasure to assist you!
Wishing you minnie magical memories :-) Allison V.
