I have an unused re-assignable 4-day park hopper in my Disney Experience account. I currently also have a DVC Gold Pass. I would like to apply this park hopper toward the cost of the renewal of my pass. Since the annual pass renewal costs more than the 4-day park hopper, is there a reason that I shouldn't be able to do this? Or do they only let you apply the cost to another pass. Can you "upgrade" to a renewal?
