We were at California Adventure today and got rider swap at Guardians of the Galaxy. Today was their first day of electronic rider swap. If you're doing the swap, make sure everyone who is swapping is at the podium with their tickets. Don't let the riders go ahead through the line once they've approved you for rider swAp. All tickets attached to the swap have to be scanned in order to be allowed back on the ride. It's basically another fast pass attached to your account. When you g o through the line e, you'll scan your ticket just like for fast pass.
