Return of the in-laws

So the in-laws are back today for 4 days. Really not too bad in terms of duration. However, my in-laws don't seem to get that people need personal space. They show up as soon as they awake and dressed and don't leave until they want to go to sleep (usually my husband and I are practically falling asleep on the couch at that point). Its nothing personal (ok, maybe a little bit personal) but they drive me insane. All I want is for them to find something else (besides me and my children) to entertain them for a few hours everyday. Is that really too much to ask?
