I want to some something nice for my whole family this Christmas but not sure what?

Now to clarify it's not like a family of my own, I don't have a wife and kids but looking to do something nice for my mum, siblings and their kids.

Now I can't do an outing as we all have different schedules, I just want to do something that will make them happy, can't do money in a card, I mean I could but won't be much, not really much of a warm feeling worth anyway.

Any ideas
