Went to WDW last week. EMH's are good in the morning. Still, nobody want's to get up. I believe it's the single most important thing you can do for yourself to avoid waiting in long lines for the headliner rides. Evening EMH's are a bust. It's easier to stay up than to get up. NObody leaves the park. They were giving out fastpasses to Winnie the Pooh last Friday for a return time of 1:15am. Unless your in it till the bitter end (say maybe 2:00 am) there is not much benefit to staying late (waiting in line wise). Still, the park is lit very nice at night and is pretty to walk around in.
