Ok. I know different variations of this question have been asked and answered. Don't yell at me.

One of our groups orders has 4 wristbands and 1 camping pass.
Plans have changed and 3 of those people are taking the camping pass and going separately.
From Coachella.com: "If you bought multiple festival passes and one camping pass, the camping pass will only be valid with the first one from your group that arrives."
Now, if the one person that is not going in that car anymore arrives before them, will their car camping pass not work?
Is there a way to call Frontgate and change this?
We don't have enough passes to trade with them because our other orders have car camping passes on them.
