re: Champions club question…

Wrist bands are no longer used. They’ll stamp your hand (and your son’s) with ink that appears under UV light AFTER they scan your ticket at the door to the lounge. No one will prevent you from swapping out seats as long as you give your daughter and grandpa your tickets (a screenshot of the ticket on your phone will suffice). But they could be stopped at the door to the club area should they try to go in there since they won’t have the hand stamp.
