To be honest Christmas is the one time of year everyone in the family is off work. So yes we did tend to all either end up at my mothers or mine for a massive roast and I used to buy crackers and the kids would have a lovely time running riot all over the house and we got to catch up with eachother. The kids would all really look forward to coming to mine for a roast, I did turkey occasionally as well (the halal butcher would take orders for turkey's and lots of people would order them), altho I'm not a massive fan of turkey (possibly I don't cook it right) and my mother loves brussel sprouts.
My best friend (also Muslim), has the same experience of Christmas, they also do secret Santas and have a lot of fun.
I do now I suppose celebrate Christmas as my in-laws are Christian, and I would not dream of refusing or refraining from joining in the celebrations with them as it would really hurt their feelings and they are the kindest people I know and have swept me and my DC up into their family.
I've always maintained Christmas is my most favourite festival that I do not observe. How is it even possible not to be a part of it, every street is lit up, we get time off work and school, the TV is full of Christmas movies loads of our friends celebrate it.
Seriously sometimes I feel Muslims are set up to fail, we're damned for not integrating and then hated for integrating.
And if anyone so wishes to do you're all welcome to celebrate Eid with us, I've known some non-Muslim people who have tried to observe Ramadan and fasted with us too. I usually hold a massive barbecue at mine for Eid (when it falls on summer) and everyone who wants is invited, the more the merrier.
