This palace opening hours are 9am to 9pm. I visited this palace just before 6pm, initially hoping to stay until dark to capture the compound with its lightings. However, the palace is rather small, with only 6 buildings in total. As such, I spent only an hour here and left, not willing to wait till sunset around 8pm.

The buildings architecture and design are generally the same as other palaces. One unique building is Jeonggwanheon Pavilion, built by a Russian architect, incorporating Korean and Western designs. This pavilion was used for banquets for foreign visitors when they visited the palace.

We ventured here for the free rental of Hanbok, and the changing of guards performance:

Changing of Guards ceremony 11:00(1st Time) / 14:00(2nd Time) / 15:30(3rd Time)
Closed on Mondays.

We queued for the Hanbok at 1300, as the sign stated that the counter will be opened at 1330.
The counter eventually opened at 1345, with crowds over-powering the queue. We voiced out to the crowd and the attending lady in charge. Yet, the lady in charge replied that she only attends to the people who approached her first, regardless of the queue.
Hence, we voiced out to the crowd that there was queue and be sensible to those who have waited for 45mins. We were lucky as the crowd were English speakers and they take heed to our comments.
Beware of the lady attending to you, she was rude and abrupt.
Well.... we were here for the Hanboks, just swallow what her comments were.
