Sounds like a lot of fun. I have to SR before, but what you described might is worth a new visit. lol

I would recommend to write a small report after your trip to Vietnam with info about your hotel. It might be helpful to other travelers. I'm honestly surprised that even websites specialized in gay travels don't mention how strict the guest policy can be in Vietnam. It was a bit of a shock for mew the first time in there.

You mentioned Taiwan and HK. I guess those have been previous travels cause as far as I know those two places are still closed to tourists.
