I agree with the PP's.
We had ADR's at Yak & Yeti in November that were right at park closing. We had a great relaxed dinner with no rushing. After dinner, we took the long way out of the park, and turned it into almost a 45 minute walk.
We stopped and took pictures in several areas and enjoyed how different the scenery around the park was at night. There were CM's posted in various places to insure we couldn't backtrack or go into areas that were already closed - but they were all very friendly and some of them even volunteered to take a few pictures of us.
The only issue we ran into was that they had ceased regular bus service to all of the resorts, so we ended up on a bus that went to 3 other resorts before eventually making its way to ours.
All in all, it was a very enjoyable evening and we loved our walk through a nearly deserted AK under the starry moonlit sky.
