Other notes:
* It is crowded for sure, you'll have to get used to less personal space and more noise
* Wear a mask, you are visiting during crop burning season so air quality will not be good
* Obviously only drink bottled water - this is valid across most of the developing world
* DO NOT hand out any money to panhandlers/con artists (including children)
* South Delhi and Central Delhi are the more affluent parts of Delhi, based on your concerns you might want to limit your excursions to these parts of the city
* Take it easy, just enjoy the sights and sounds
