Why am I imagining two 30-person polycules rumbling over one (or more) unethical hookup between them?

Also: how does the legality of physical assault work in international waters? I would love to see Legal Eagle take this one on.

60-person brawl [...] 5 different floors

Honestly, that's kind of epic. It has the makings of a movie with this many people and locations. Maybe even a Knives Out sequel.
