I am planning a vacation to Vietnam for early 2017. Vietnamese New Year is Jan. 27 + 28 and Tet is Jan. 29-31. If I arrived in Vietnam Jan. 4 or 5 and was gone by Jan. 20 will I avoid travel problems and higher prices? If I wait to arrive Vietnam until after Tet, how long after Jan. 31 is it safe to go? I can enter through either Hanoi or HCM City.

Because I will be using AA miles before the devaluation I have to finish this trip before Feb. 15, 2017 the last day to travel under the current miles rate. I'd prefer to go in late Feb. or early March but it will take many many more miles for J or F seats.
