We went there New years day and went to tusker house for dinner. It was open until 8pm that night I believe.
We got out of dinner maybe 630 to 645 and the park was very quiet almost deserted then. A number of the attractions had closed by then. No safaris and no nearby Lion King show still running. That may change when there are after dark attractions and activities to do. But I don't think there were even enough lights back in January.
