I would be fascinated to hear from kinksters who have run similar events.
They are keen on controlling contact and fluid-borne infections, but don't talk about airborne infection control. Rationalists have a "COVID is over and RSV sounds like a Linux distro" party line which separates them from alienated nerds I know.
Events I attend which combine alcohol and a risky physical activity have a one-drink maximum, or once you drink alcohol no more playing for you, not a subjective "Don’t drink too much."
