I dont believe certain levels of Aps would be effected as it would likely be one of the "perks". Lower level Ap holders would likely be able to pay extra for the benefit. As Disney says in their contracts for APs and DVC owners, all entry to the parks and benefits are subject to change or modification. As a DVC member you pay for access to the resorts, not the parks. Access to parks is ticket or pass based, so they can easily change things up under a new normal to ensure they dont have to shut down again in the case of another scare. And honestly it is smart of them to make changes they had been considering now.
