Hey @Chelsblu -
You certainly can relist the tickets you don't want to keep back on the site. What the issue might be though is that the parking passes would need to be listed separately on our PARKING PASSES ONLY event for the game. Even though the listing you purchased had tickets and the pass, this option would only be available to certain sellers thru their season ticket holder account.
I'll send you a private message here in a second so we can go thru the relisting process together. Thanks!
