The attendance numbers between these parks is not that much different.AK if it likes it or not has zoo characteristics written all over it,and zoos just don't open after dark.DHS's theme lends itself more to nighttime operation.Until AK gets a nighttime show and they build Avatarland with a major E-Ticket attraction and with flourescent colors that glow at night I just don't see AK staying open past 6-7pm on a regular basis.Epcot closes at 9pm pretty much all year,in the Holidays they extend it to 9:30 and I think sometime last year or in 2010 they had a 10pm closing time either on Fridays or Saturdays I think during the F&W Festival.I agree that at certain times in the year I would like to see them close later but on the other hand I'm glad that they at least always stay open until at least 9pm,DHS might stay open later than 9pm sometimes but other nights they're closing at 7pm.
