I was there two years ago and although I had a tripod with me I didn't take it out in the city. I took two Hasselblads, one with a 50mm lens and one with a 150mm, Delta 400, a couple of filters and a light meter. I used a daypack and left the rest of my equipment in our hotel room.
Don't worry about what to shoot every where you go there are images just waiting to be made. Buy a pass for public transportation for the days you will be there. It is the easiest and fastest way to get around. The people are friendly and helpful and in general easy to engage in conversation. Don't forget to eat ... great food!
