We need sufficient time to see items displayed of King, Queen, and architecture of palace.
One of the best tourist destination of Karnataka is sprayed in a vast area, including garden, buildings and museum.
This is very well maintained and items used by King, Queen, their dresses, items used during war, are displayed, and neatly preserved.
Dashara festival of this palace is very famous, whole palace is illuminated, elephants decorated and all rituals are performed as we are living in a king dynasty.
Best time is to visit during Dashara but some rush may be there but this will be a quique experience to see lot of people.
I recommend everyone to visit mysore, nice tourist place.
