I have changed plans again after a number of conversations with specialist travel medicine professionals and daily checks of WHO website, I am going. Three days in Bangkok to reacclimatise myself with being overseas, then two weeks in Vietnam.
The suggestion of a 10-17 is a teaser, since I have one and it's very light and goes much wider than the 15mm. I expect that the 16-85mm will be the lens I use almost all the time, then the 21mm as a lightweight walkaround.
Have a great trip,stay safe and post some pics when you get back
