I've done evening EMH at AK twice. KS always stops shortly before sunset. When I did EMH last August, the CMs said that KS wasn't open. However, I walked over anyways and was so thrilled to find it open until 7:00. AK was open until 8:00, but sunset was closer to 7:30. As an example of how few people were there, I stopped in a rest room in Asia, and no one else came in the whole time I was there. You know, that was a creepy feeling-going into an empty restroom in AK! It's a great time to see the characters at AK. I went to see Eeyore across from FTBBQ, and I didn't have to wait in any line.
Oh, about animals on KS at that time of day, I really didn't notice any more than usual. What I did notice was one less. Does anyone remember the big male lion who lies on the rock up on the hill? I've been on KS about 10 times, and this was the only time he WASN'T there.
