I actually registered just to post this comment!

(I have been a lurker for some time and really enjoy reading all of the threads here!) I was getting nervous myself (since we'll be visiting Disneyland in Sept) about the 7pm closing time and have been following this thread closely.
I went to the Disney website and sure enough, the Sept calendar *does* say that it is closing at 7pm... BUT, if you click on the "View Daily schedule" link on the calender, there are some discrepancies. For example, if you click on Thurs Sept 5th, while it says it's closing at 7pm on the calendar, the daily schedule shows Disneyland open until midnight!... Same with Sept 10th (Tues): it shows D-Land open until 7pm, but the daily schedule shows open until midnight.
Anyway, I just wanted to throw this out there that maybe they've messed up with this calendar, and it *Won't* actually be these hours that are posted.
...I will keep my finger crossed.
