Voice of dissent here. AK (Pre ROL) is a great park to arrive after 2. Especially when the park is open until 7 or later. See all the people above who say they leave by noon, one, three? Yup, they are gone and I am walking on EE, Kali and KS.
ROL and the nighttime activities will put a damper on this.
I remember when AK had Evening EMH. It was awesome to ride EE and Kali in the dark. Even Cheesy Dinoland is cool at night. All those round lightbulbs light up, it really does feel like a carnival (for better or worse)
