We were at Epcot for EMH evening hours last week. The following Futureworld Pavilions closed at 7pm... Living Seas, The Wonders of Life (or whatever it was called... the one with Cranium Command and Body Wars) and The Land (which is closed for renovations and the upcoming premier of Soaring in May.
Mission Space, Test Track, Universe of Energy and the Imagination pavilions were open late. I'll also point out that they were open until MIDNIGHT, not 10pm, so basically EMH gave you 5 extra hours in those pavilions!
