I am headed to WDW at the end of the month. I have some park hoppers from my last trip. I wrote on them what is left. My parents were also with us on that trip, and they have given me their room keys from that trip that have I believe 2 days on each of them, but not 100% sure and not sure if they had they hopper option. They were from a Dec 2004 trip -- right before the MYW tickets were used. Anyway, my dad gave me their cards with the admissions on them and told me to use them. They are elderly, have many medical issues, and won't be able to do any more trips to WDW. Two questions -- can I use their tickets? They would be willing to give me a letter stating they are letting me use them (their signatures are on the back of the cards). Also, is the only place I can check what is left on any of these tickets at one of the parks? I know they used to be able to do it at the resorts. Because I am not sure exactly of what I have, I cannot pre-purchase tickets.
