I don't THINK they have the capability of checking park passes. But, you could always call ahead and ask.
It used to be that you could call Guest Services and read them the hopper serial number on the back of the ticket and they could tell you over the phone. But with all the changes in customer services over the past few years, I don't know if they will still do this or not.
I know this won't help your current situation, but we usually make a small "hash mark" on each hopper for each day we've used it. Helps these quickly aging minds keep things straight!
