I'm currently in hanoi and considering visiting hoi an. People seem to love it, but from the description I'm a little afraid that everything there revolves around tourism which isn't what I'm looking for. Is there more to hoi an than tourism? Are there places where I can just roam the streets and watch people who aren't visiting or catering to people who visit the country? Are there other parts of northern or central vietnam that would be better to visit? Thanks for any advice.
