I wouldn't have moved the furniture. As much as I love my husband, unless we were in seperate rooms, in which case I WOULD squeeze into a twin bed to sleep next to him, sleeping only a couple feet apart wouldn't bother me. I just don't think it would occur to me.
That being said, like others have already mentioned, if you haven't given them a reason to believe you disapprove, they're not really in the wrong. UNLESS, the floors are wood, fake or real, and could potentially be scratched. I would then find it ballsy and kind of rude to risk it.
