upgrading park tickets

[tominmpls46]

I bid and won 4 park tickets that expire this year but I wont be able to get down there. Is there a way I can convert / upgrade the tickets so they dont expire?

I'm going to say that those are probably some sort of complimentary ticket. CMs are given tickets that expire after a certain time, sometimes, guest recovery will give out tickets for some issues that possibly have an expiration, on them, etc.

The value of those types of tickets is zero, and that is the value that will be offered if you need/want to upgrade them.

Basically, chances are no, you will not be able to upgrade or otherwise alter the terms on those tickets.
