Late October Southeast Asia - Need Help weather

Because of my job and other circumstances, November through March cruising to Southeast Asia is very tough. Azamara came out with a 10/16 to 10/31 itinerary for 2020, which I booked. I am having second thoughts and would like advice.

We'd fly out to Hong Kong and arrive on the 14th. I know Hong Kong rainy season ends in October and everyone says that the later in October, the better. I think we could be risking a tough pre-cruise visit to Hong Kong. Viet Nam is probably okay with the exception of Danang (Hue) where it could be awful. Bangkok is October 25-27 and some say that is close enough to November not to worry. We end in Singapore, which is supposed to have nice Octobers and Novembers.

Most of my concern is Hong Kong (2 days), Bangkok(2.5 days), and Danang(1 day). For those who spend time in this region, am I overthinking this or is this cruise during this shoulder season very risky?

Thanks, Len
