Sounds like they need a good talking to. Why tip-toe around and let them think you approve or are even considering this "option?" Put your cards on the table, ask why they would even consider arranging a visit if it is under these circumstances? Don't wait for them to come up with any bright ideas, go ahead and make the suggestion you have in mind. Either it will happen or it won't, but don't subject your father-in-law to a holiday in the Twilight Zone. And you won't enjoy your vacation knowing he's in that kind of place, so why bother considering it?
