They are usually out a couple months before, so I would start looking for them around September. We've been there in early November and early December, the last few trips. MK is usually open till 6pm/7pm. MGM is usually open till 7pm, Epcot hours don't change all year, and AK closed around 5pm. Spectromagic was only two nights, Tuesday & Saturday, I think. You can find the projected hours somewhere on these boards, I think. Look at the top of the home page.
