The big question is can she transfer from her power wheelchair to a ride vehicle. If she can, must rides are set up so she can go through the line and then transfer. If she cannot transfer then the rides are limited but the shows are not.
In MK she will have to transfer to a manual wheelchair to ride Pirates of the Caribbean.
Winnie the Pooh ride will take some power wheelchairs.
HAve to thing of others that the power wheelcahir will go on.
