People who spend ages cleaning before you leave - don't you find that by the time you've done the last minute packing and dragged all the cases and people into the car, then it looks like you hadn't bothered anyway?
Same as Caribbean, I don't find this. The house was nice and clean when we left, and nice and clean when we came home. The cat was home (with regular cat sitter visits, of course), and there was extra cat hair and a surprise hairball upstairs, but otherwise nice to come home to a clean place, and go to sleep in clean sheets etc.
My reason for cleaning is that I used to feel quite down coming home after visiting places much prettier and nicer than home was, back when we lived in a small flat, so I tried to do what I could to lessen that, and it's stuck.
