Since EFW typically closes at 7:00PM and EWS closes at 9:00PM. Can I assume that evening EMH's run to 10:00PM and 12:00PM respectively or are both side of the park open till midnight?
Epcot's EMH are from 9pm-12am. Some FW rides (Soarin, Spaceship Earth, Test Track, Mission Space) stay open until 9pm anyways. Some rides (such as Journey into Imagination) close at 7pm, then re-open at 9pm for the EMH.
