seems like the local law would apply.
given the nature of business I can not imagine NORMAL couples wanting to have these sexual “alternative lifestyle” persons in their midst.
Perhaps they should have a seperate resort for the 1% of the 2% that want to simulate normal marriage.
I faintly recall that there used to be a couple of such resorts many years ago. They got closed pretty quick after some sort of an environmental problem. I guess the time is ripe to open new ones, for the same purpose.
