Why would it be abuse if you just asked for the data to be deleted? As long as you do not misrepresent things and do so politely, of course.
If Disney wants to spent time and money and reputation to figure out if they legally need to delete the data they collected about you and only do so when that's the case, then that's their choice. Same as it was their choice to collect data in the first place.
If they instead want to be nice and consumer-orientated, as they like their public image to suggest, or at least save some bucks, then they will hit the delete button. They gotta have such button by now anyway for legal requests from Californians.
