Bank the Early Entry rides, then TRON before it costs you more
Seven Dwarfs Mine Train and Peter Pan's Flight are both on Disney's Early Entry list for Magic Kingdom, so Early Entry guests start there while everyone else waits for the 9am open. TRON Lightcycle / Run, Big Thunder Mountain Railroad and Tiana's Bayou Adventure aren't in the Early Entry lineup, so they open to everyone at once at the official start. TRON is the single biggest time cost in the park, so it comes first for rope-drop guests and right after Fantasyland for Early Entry guests.
