For those with more time or are interested in shopping, head over to Grand Indonesia or Plaza Indonesia. If you have less time, skip the National Museum of Indonesia and spend more time exploring the old buildings of Kota Tua. However, do note that some parts of Kota Tua are best explored in group rather than alone due to safety reasons. Don't forget to bring sunscreen, comfortable shoes, and an umbrella as Jakarta's weather can be unpredictable.
