Caroline would like a small house party Christmas eve but Fallin wont have time to make it a thing so it will be small family affair
Daniel will be at the obligatory Selwyn party that I need to talk MJ and Lauren into hosting
Hermione will be hosting a Longbottom Prewett affair if her sister isnt already
Malou will be working
Percy will be spending a quiet one with Cat and her kids in the Adlard hogsmeade home
Sisse will be home, she gave everyone their gifts and homemade cards before they left
Sybille will very reluctantly be home.

Asha and Galina have no plans.

Edit: Asha will be with the revs at the Augurey.
Malou will be attending a Christmas eve midnight service in London, then working the early shift at St. Mungo's before a supper with her godmother's family and then back home for a quiet night in.
Galina still has no plans but is likely going to rather more reflective and thoughtful then typical. Holidays remind her of her past and if no one is around she plans to wallow just a tiny bit.
