We're going to be there the first two weeks of October. Here's where I'm frustrated. This is NOT the same as HS. First off, HS has always had nighttime hours. Secondly, HS does not have as many attractions that will be different experiences at night. The only one at HS that qualifies as 'different' at night is Tower of Terror.
Disney has been promoting AK as a new nighttime experience. There is more to that experience than ROL. Sunset/Nighttime Safari, Everest at night, the Tree of Life. All of those are unique and different experiences than what you get during the day.
Given that, if AK closes at 7:30, even if there is a ROL/JB show at 8:00, after park closure, you just won't have any time to do those other things. When Sunset is 7:10, how do you do a sunset safari (25 minute commitment) and ride Everest both before 7:30, and then make it over to ROL/JB by 8 o'clock. The timing to do all that is not feasible.
