DSIL and child are visiting from overseas this Christmas. My elderly FIL and MIL live an hour away. They are coming to us for Christmas- no problem, we've a bigger house, I like to cook and we all get on. My sister will also be coming. I assumed they would come for 3/4 nights which was fine.
Now they want to come for 6 nights - we live rurally so thats a huge amount of shopping, catering and organising and I think I'll be run ragged. None of them really cooks so it'll fall to me. AIBU to ask that they return to the parental home after 4 nights. I don't want to be mean but I do want to enjoy Christmas
