I don't mind if close friends drop in unannounced for a short visit. My house is usually in good enough shape for friends (and they take us as they find us), and I can more often than not whip up a quick meal.
On the other hand, people don't stay overnight in my house without an explicit invitation. If friends or family are going to be in town and they want to stay with me, I need to know arrival AND departure dates, what they're planning to do while they're here -- whether they just need somewhere to sleep, or whether they need to be entertained.
I've found that "Oh, give me a call when you get in to town. We'll get together for dinner." works really well to deter people from assuming they can arrive and move in.
BJL, I would also be irked. Hope you have fun with your FIL and family anyway, and hope it's not too much work.
