I have a feeling there's more to this story -- a single adult guest isn't that much trouble.

In some ways, I'd think hosting company is easier for parents because they have a regular schedule, they must prepare meals, probably have a full fridge, etc. I always have to go out and buy food when I have company because I don't keep much in the house.

Is there literally not enough room for someone to sleep? Can you sleep on the couch? Have there been problems in the past?
