Crazy while we stay with family any other time of year, we used to rent a cottage to go "home" for Christmas since before DD was even around. I tried last year but the price was extortionate for 1 we'd enjoyed before and DH just got cold feet about covid so we stayed here. There are others popping up on some sites which might be ok, or a DSis would let us stay as she's not taking sharers for the other 2 rooms in her house (that she rents, but landlord is very accomodating, as it is DF!) also due to covid - and that would be a far quieter house!
DD's shelf is various chicken and turkey meals, bean mixes, potato wedges that she will eat, sugar free ice cream, some fish, lots of fruit for smoothies, thin bagels, ....she has got very fussy about food, won't eat red meat and thinks my cooking is dreadful as I use oil and butter, sometimes cheese and cream, and don't use anywhere near enough chilli and spice...so if she will cook for herself, I am happy to facilitate within reason - it's just going beyond reason at the moment. (There is a tonne of fruit in the fridge, and various meals as well, for her...but in true teen fashion, there is "never anything to eat in this house" 
).
I just remind myself, very frequently, that "A (girl) Guide smiles and sings under all difficulties" (just don't ask me what the other 9 parts of the Law are...I usually only remember about 3 of them 
).
