Yeah, as in my experience, it's best to visit the middle part of Vietnam since the price is better and not so crowded all the time.
But also it's not very easy to communicate since they don't speak much English, even though it has some improvements now but still all kind of terrify.
So in summation, you might want to get some help in Vietnam, someone who can ACTUALLY speak English and also a native. It can get messy, trust me.
