Robin, with all due respect, I'm not clear about why you are in this thread if the room is separate from your dwelling or sleeping space.
We are talking here about guests having loud (or messy, in my case) sex in the room right next to you, where you, the host, are trying to sleep--or, if you, the host, have kids in the house. So, your situation does not apply. In fact, you should delete your responses since your situation does not apply. You can put your opinion about other people's situations, but you do not have the personal experience in order to understand, fully, what it is like.
I live in a tourist town, Wilmington, NC. Guests who come usually come for a reason: wedding, beach, sightseeing, visiting. When a couple shows up for a weekend in Wilmington and spends most of it in the room having sex, I feel I have an obligation as a host to let other hosts know about this.
