We always go to PIL for Christmas (DH, me, 4DC and 2 dogs) plus BIL and SIL. MIL has called 'just checking' that we re going this year too. Apparently she needs to start her 'catering arrangements' now 
We loooooove going there, everyone has a wonderful time, but after the palaver at Easter with B/SIL mad PFB stuff here I'm not sure it's going to work. I've said that I'll need to check with DH and I'll call her back but I'm really not sure that everyone will have a nice time. That said I would hate to upset PIL as they are truly wonderful people, also the DC adore going there for Christmas. I tried to ask where everyone was going to sleep, but she sort of brushed the question off. I can't cope with another round of 'DN has to have her own room so your DC will have to sleep on the dining room floor' 
Gah it's September FFS
