I'm not a fan of morning EMH because well, we aren't morning people. However, I love late night EMH in MK. We make a point to always be at those because the later it gets, the less crowded it is and we can usually walk on most anything we want.
Glad it works for you, unfortunately that's never been my experience. I loved 12am normal closing at MK because as you say, you could walk on the rides. EMH nights not so much, lines got shorter towards the end, but nothing like a normal night.
