I actually took the direct approach and asked W what the sleeping arrangements were for xmas, her reply was "I haven't a clue" this is her typical reply to a question she doesn't want to answer. (others are I don't know, or it's up to you).
After a quick rethink she said her parents were staying over. Yes I know that, so is my mom. Then she said my mom will have D6 bedroom, (instead of MIL & FIL) and FIL sleeps downstairs. So if my maths are correct that leaves me still in the small room and W, MIL, D6 in the main bedroom. Not the best solution and I think W just thought it out on the spot.
I told W , I'll sleep downstairs and she can arrange everyone else more evenly upstairs, but she just ignored me and didn't respond.
So anyway I know what's happening now.
