Keep the 825 ADR, show up at Epcot by 730, you’ll be let in with all prepark area, go straight to Garden Grill and check in. Most likely you will be seated with 5 mins. of checking in, even though that will be well before your ARE time.
As soon as you sit down, ask for your check and tell your waiter you’re trying to make rope drop.
Pay, eat, visit characters and leave around 840/845 and ride Soarin before everyone else.
With prepark ADRs, the times generally don’t matter as long as you’re before park opening … it’s more about when you check in.
