We have recently moved into a larger house with a spare room.
Usually inlaws would stay in a hotel nearby when they visit (they live 6 hours drive away so come for a few days).
My parents will continue to stay in a hotel as they like the break/holiday aspect of it.
Dh says it would be unfair to ask his parents to fork out for a hotel now we have room. They can afford it and they stay for about 3-4 nights.
I probably am being unreasonable but I hate the whole sharing of bathrooms etc with MIL. I just don't want them here when i wake up and when I go to bed for 4 fricking days. They drive me crazy, wind the kids up so they don't want to go to bed etc etc
