Our experience for AK after hours in May was fantastic. We arrived around 5 we already had park hoppers so just went through the regular line and got our wrist bands outside of Discovery Trading co.
Our hours that night were 9-12 but regular park close was 8:30.
We picked up a couple of fast passes for other rides and rode Everest 3 times before park close and then at park close went right back to Everest. No line at all and the CM’s were letting all AH people in right at park close. We rode that 5 times back to back, then we got popcorn, then we walked over to Pandora getting ice cream along the way. Rode FOP twice, absolutely no wait other than the time it took to do each pre-show and walk all the way out and back in, but we are fast walkers. Then did Navi twice, no wait, then did FOP again twice, no wait, did Navi again twice, no wait and did FOP twice again, no wait and then walked around Pandora taking night time pictures with no people in them at all. Finished the night with 1 more FOP, so our total for just AH was 7 FOP, 5 Navi, 5 Everest. No wait for anything.
My husband said if they offer these again next year (we did all 3) he would absolutely do all 3 again, as all 3 nights he couldn't believe how many rides we got in and how great it was not to be in big crowds.
