I appreciate the pedantry; but, there’s a significant difference between several random someone(s) having travelers diarrhea in a shared bathroom and my family.
The point is multiple people sharing facilities get discounts. It’s nothing more sinister than that. The hotel charges per room, and rooms include facilities. The costs for the hotel don’t depend on how many people are staying in that room.
Right, but my point is that you're now no longer complaining about the concept of offering discounts for room-sharing. Now you're complaining that there's no one you would be comfortable sharing a room with.
