A lot of people have wanted to have their ashes sprinkled inside a Disney park.
As somebody who gets to visit Disneyland and Disney World on a somewhat regular basis, it doesn’t matter how often I am there, I never want to leave.
Nobody wants their favorite attractions at Disney World closed for a biohazard cleanup.
Grande would almost certainly be banned from Disney World for even trying, and based on the way she talks about the parks, that would be the worst possible punishment.
