just got back from nha trang and ho chi minh city a few weeks ago and absolutely loved it, except for the typhoon in nha trang when we were there but at least it was sunny the day we arrived, got to walk around the city a bit
ho chi minh is crazy busy and super humid when we were there but a great experience nonetheless...the conversion is crazy and everything is super cheap over there...hard to believe how far $1 CAD can go...
definitely would love to go back
