In late November, AK was open til 8:00, and at that time of year, that's several hours of dark. There were no animals out, but the there were hardly any people there either. My guess would be, therefore, that it would be a good time to ride EE. I took the train to Conservation Station and I was the only one on the train, either way (the walk from the train station to the building was interesting in the dark). There was absolutely NO ONE in Africa. If you want to see the characters, this is a good time-I walked down to where Pooh and Eeyore are (across from Flame Tree) and the only one there with them was the CM. I rode Triceratop Spin 3 times in a row without getting off (I did it so I could get the great views of the Tree of Life lit up in the dark). I thought it was an absolutely great time to be in AK. DH and I are going to WDW in May, and I've already told him that I don't care what else we do, but we MUST do Evening MH at AK.
