It appears that beginning today at Epcot all guests were checked in at the toll plazas and even if you don't pay to park you were given a receipt to park. It slowed down the process of parking of course. Epcot is the test site and it is expected it will soon rollout to all four parks for parking.
It appears to be a way of tracking and making sure everyone who is supposed to pay is paying for parking.
