I'm having all my family to stay for 4-5 days over New Year as my younger brother is returning for a visit with his family after several years abroad - there'll be 12 of us & I'm looking forward to it. My parents (who live 280 miles away) have suggested that they could come for Christmas as well, as they don't have another invitation. I find it hard to say to them you're not invited for Christmas. I would actually like to spend some of the holiday period with my DH, DS and DD without visitors. Am I being mean and selfish? What should I say to them?
