10 cities I'd like to visit and one thing I'd like to see in each of them

I don't have a lot of "things" I want to see. I really just want to wander semi-aimlessly and see what adventures would come to me.
  1. 1.
    Amsterdam - Red Light District (except for this time I'd actually choose a woman in a window)
  2. 2.
    Cairo - the Nile as it snakes near the city, the nearby pyramids
  3. 3.
    Bangkok - I just want to wander the streets for a few weeks with no agenda, and see where else in the country that would lead me
  4. 4.
    Mumbai or Delhi - same story as Bangkok. I really just want a backpack of clothes and necessities (so not much, really), a limited budget, my wits, and no agenda to become lost and see where that leads me
  5. 5.
    Hong Kong - see above
  6. 6.
    Tokyo - also see above
  7. 7.
    Paris - see above, but with a bigger budget to eat out at European prices
  8. 8.
    Rio de Janeiro - see above, same as paris
  9. 9.
    Budapest - see above
  10. 10.
    Cape Town - see above
