I agree with your points, just want to add: The best way to connect with the culture and people is to get a local job, or studying at a local university or at least taking courses. EDIT: Basically become an immigrant, even if it's only for a couple of months. Ideally don't plan your return, make your journeys open ended!
I have a question to people saying "get a local job" What kind of jobs do you mean?

I don’t think you need to worry about that, in more exotic locations you will be so out of place anyway and they will have no way to judge if you’re rich or poor. And in any case people generally don’t care that much about others.
