Rider swap question

If I have FPP for me, DH, and DS6 for 7dmt and my mom is staying behind with DD2 is this eligible for rider swap? Not quite sure I understand the process

Yes, you, DH and DS6 can ride with your FPP. When you enter the line, make sure your mom is there with DD2. They will give her a rider swap card. When you are finished riding, she can ride with DS6 and someone else through the FPP line with the rider swap card.

Does she have to halos have the original FPP or no?

No, she doesn’t.

Well, we have never needed it. I don’t know what the official rules are.
