I meant exiting GE, not the park.
And the GE system starting June 24th is a Virtual Queue system. So let's say GE holds 5,000 people. When the park opens (And Disney Hotel Guests should get Early Entry To DL every day, the 3 day or more Tickets Early Entry is every other day, and only one per trip), they go right into the area. Then the DL App starts handing out Virtual Queue tickets, starting at 5,001. But those folks numbers are at the top of the list, so you get in a real queue. Lets say 500 people get in that. Then your number (5,501+) is your place in the virtual queue. 250 people leave GE, so the first 250 in the real queue enter, and then numbers 5,501 to 5,750 get the Push notification on their phone, or those who went to get the paper version, at those machines, and at the real queue entrance will show the highest number to get into the real queue. And the process repeats.
Unknown is if your queue number expires or is good for the rest of the day. My guess, like FP's there will be a grace period, say about a hour's worth, so you can finish what you are doing when you get the Push notice on your phone (riding, eating, etc.) then head to the real queue. Also, EVERY member of a group must actually enter the park with their ticket/AP to get a queue number, so one person can't get up early, check in for the group, and then go back to get the rest of the group.
That is how I read the rules.
