We had to fly into Danang from Hanoi as the Hue airport was under repair. What was supposed to be a two hour trip turned into three hours quite late at night as apparently a lot of the trucks use the road at night to avoid the police. The road was quite rough and went through a number of mountain passes which slowed us down. We missed out on the views due to being night time but the lights of Danang looked fabulous
Allow plenty of time if you are going by road and watch out for the suicide drivers in the buses!!!
