My family purchased four five-day park hoppers in 2017 from Undercover Tourist for a planned vacation. For a variety of reasons, the trip never happened and the tickets “expired” in January 2019. We are finally taking the vacation in November of this year. I understand that we can get credit in the amount of the original ticket cost (maybe value?) towards passes for our upcoming trip and that I can make this transaction only at the Parks, but is there a way to determine what the cost/value of the original tickets is so I can know in advance how much it should cost me?
