When the park closes at 5:00, EMH there means it will be open until 8:00. I've been to at least 2 evening EMH at AK, including one in November. Although I really loved it (I love AK), there's very little to do after dark, and in November it gets dark. I went out to Conservation Station after dark, no one else on the train, and it's a long, dark, lonely walk to the building when you get off the train. But if you want to see the ToL lit up, ride TS. Because of the beautiful view of ToL at night, I rode TS 3 times in a row.
