I became a museum girl when I started exploring places. Back when I was in school, I only see a museum day or museum trip as a sidetrip to explore other things outside school (those were the days when parents were so strict)
Love this gallery too!
Things not allowed in the Museum:
Food and Beverages
Touching of displays
Tripods and Monopods
Large Bags and Carriers
Pens and Art Materials
There is a baggage counter at the entrance where you can leave your stuff.
National Museum appears to be a really good venue for events.
