We want to visit Disneyland on a Friday thru Monday next month and purchase Deluxe Annual passes at that time. Friday and Saturday are blackout dates. Can we purchase 3 day hoppers ($149 online same as gate price?), use those for Friday and Saturday and then on Sunday upgrade to a deluxe paying the difference of $120? That would allow us to visit over a blackout weekend without having to buy the premium $389 pass. Is this allowed?
