Name changed just for festive fun!
Long story short PIL moved to another part of the country 2 years ago, pretty much a full days drive just to get there. They now come down intermittently throughout the year and stay with SIL as she has the room but we don't.
Normally at Christmas we half the day, morning with DH's and afternoon at mine. Makes everyone happy. This year however SIL is saying we must host PIL for Xmas.
DH explained we don't have the room for anyone to stay over and we have already accepted to go to my mums for Xmas dinner as we thought we would see them as normal during the day.
Its now causing a bit of bad feeling as PIL want to come for 10 days in total but SIL says we must have them for at least 5 days and basically tough shit to my lot already having prepared for us to go there. Can't invite PIL to mine as they don't get on with my Dad.
AIBU for telling SIL that's it's her problem, it's her parents and if she doesn't want to have them for that long then she should tell them it doesn't suit??
