Yup! this is important for us to know the surrounding and tomorrow can walk around by our self or take taxi or what so ever to place we like to go.
Don't worry, apart from horrible experience in crossing the dare to die road, Vietnam tourism quite safe for tourist like us. No matter how you still need to be careful when in other country. Since I went there early April the weather in Vietnam, I mean Saigon was freaking hot! compare to Hanoi which is a lot cooler.
