Of course, yes, thanks Ginge, it's the occupants, not what they're sleeping in. I was using one of the alternative spellings for 18a, and wasn't quite sure of the parsing for its last letter either.
I'd better take the chance to check the one other which I wasn't 100% sure of: 5d. I have the French cold Mediterranean wind, only with the first two letters replaced by 'E', but can't find any reference to that word...?
Thanks again.
