Except for some very slow days, IOA has been closing at 8 or 9 for most of the year. Just about every day (except Grad nights and private parties) from mid March up until a couple of Sept days it had 8 or 9 O'clock closings. Yes, this is very different than past years, but they have been trending in that direction for the past couple of years, slowly but surely. Yes, MK is open more hours than IOA, but not as many as Disneyland (that was what I had stated for comparison). MK 'used' to be open until 11:00 and midnight routinely, but that is no longer the case. It probably closes at 9:00 Pm more days than any other closing time.
