For the last few years we have had a really good arrangement for Christmas. My ILs arrive for breakfast (yes, breakfast!!) at about 8.30, stay until after lunch and then my family (sometimes just my parents, maybe the odd sibling/ cousin in tow) arrive for late afternoon and stay for a buffet tea/ supper and go home at about 9pm. Suits everyone. This year however, my siblings are all going to be home for Christmas (live around the world) for the first time in quite a few years. I woul dlike to invite them to mine for lunch for various reasons, I can't deny that I would LIKE them to come to mine but my main reason is that my mother is getting older and i think it will be too much for her to host 13 people, and I'd rather she was sitting down and enjoying time with her grandchildren (who she hardly ever sees) than running round after everyone and struggling with cooking Christmas lunch on a small cooker. We could then invite my ILs round for breakfast (stay until 12ish) and see them again on Boxing Day. Do you think I would appear rude if I suggested this to my IL's? (We also see them every Christmas Eve until late, which wouldn't change)
