Probably change hours to 10pm. We went to all 3 AH last May and only AK and HS had a 30 minute gap between park close and event start. MK started the exact time the park closed but, at least in May, it was a non issue. The line wait dropped to 10-15 min pretty quickly after the party started, then went down from there. A lot of people leave after the fireworks. We started our evening at BTMR and even at 10 on the dot, it was a 5 min wait tops and by the time we rode 3 times it was a walk on. But every night is different, we were very lucky that all 3 of ours were very low crowds.when im there in april next year MK hours are to 9pm and after hours is 10pm-1am . does that mean you could expect normal hours to be extended till 10pm or do they normally have a hour gap ?
