And where can I definitely go to get an idea about KL?
Merdeka Square
32 not so hot. Take a walk through the Indian and Chinese quarters. Reach the bird park, visit the Malaysia Museum (to the towers). Leisurely enjoy juices and ice cream. Rest on the benches and chat with people. This is the best advice I can give. The day will fly by unnoticed. On average. If you don’t run back and forth but plan a route no longer than 12 km.
And to see everything around within walking distance.
