2 reasons.Maybe I am wrong here but with the exception of opening week where there maybe land closures if not park closer due to capacity, I don’t understand the sense of been at the gate for 4am. The logic of queuing 2 hours before the park opens and then running to the land and then in all probability still face a que to do smugglers run against queuing 3 hours in a themed land, with a themed que, for the ride seems folly to me. Even if the que is 4 to 5 hours I would rather stand in that with my son playing with his newly purchased droid using the Disney play app to interact with the elements in the que eating a Hondo burger (or whatever themed food they have) than sit in a car park for 2 hours after having left our onsite resort at 3am!!!! Am I the only one!!!
1) If you start at 4am and it takes 5 hours to get through smugglers run... you still have 12 hours before the park closes in the night.
2) If you queue at 4am and it takes 5 hours, mostly likely showing up at noon will take 4 hours to get in the land and 4 hours to get on the ride.
