any chance for RnR & StarTours at night in late Aug?

[newholidayx2]

or do we really need to plan an early morning to do these attractions?

If by night you mean experiencing them close to when the park closes (After 5pm or so) then you can. Star Tours should start emptying about by about 5 or 6pm while Coaster might be less crowded in the last hour the park is open.
