The normal every day route would be to turn left out the resort's front gate, then right on Epcot Center Dr. to World Dr.
According to that map, EC Dr. is expected to be closed until 9:30, but World Dr. into the MK Parking Lot should open at 8.
So of you're traveling between 8 & 9:30, the route would be left out of the resort to Buena Vista Dr., right on BVD to World Dr., and right on World Dr. to MK Parking.
If you're arriving at TTC before 8, the usual route would be right out of the resort, left on Vista Blvd. past FW, and right on World Dr., bypassing the MK toll plaza and entering the parking lot thru a side gate.
Do allow extra time in case you have to backtrack to a different route, or there's a delay getting from the parking lot to the Monorail.
