lonley planet is great.
When I arrived saigong, I thought I would like to meet vietnamess. So I didn do like western people. I just walked into vietnam, and didnt go where lonley planet says good. but I realize that we have to do with lonley planet. Please read lonley planet, and do that just they say so. Good luck.
But vietnam people who is normal person, not salesman, are good. Be careful a person, who talk before you talk.
