we were with our kids but they did very well with the crowds. More like the crowds did very well with them. We never got bumped or pushed. pretty amazing how in such a dense populated area they keep it so well organized. I guess you could call it, organized chaos.

Yes they are very tidy and organized, that's why the city can accommodate so many people. Also no chaos when in a long queue to buy things

Right, it would have to be organized and the people all need to have respect for each other for it to work so smoothly. Pretty incredible.
