DD was trained on the system. What they told her was that if the line is 10 minutes you are to direct the guests to get in the Standby line. The system assigns a return time so if it is 10 minutes and it takes away the 10 minutes that would give you zero return time.
Now they could just waive you in and override the system so at the second scanner you get green, but that is going to be up to an individual CM.... and not your goal.
Why don't you head to the characters and send someone over to the GMR to get a return time as soon as the time goes over 10, then just come back and meet you.
