Also, you say they like to check with each other before they decide if they're coming for Christmas or not. Does that mean they will only come if one or both of their siblings are there? Does this always happen or only on Christmas?
Could it be they just want to coordinate things so that they don't have to make separate dates with their siblings? Since they probably also want/are expected to see their ils/partner's relatives and friends, etc., their Christmas schedules may be quite full. They may just be trying to lower the number of dates they have to make by seeing to it that they visit with you and your other ac at the same time.
Are you flexible about the date? That might make it easier.
But does this mean that they refuse to come if they and their siblings can't all be there at the same time? That's hard to take, I can imagine. Is there some reason they're uncomfortable being with you and dh alone? Are there some unresolved tensions between you? You seem to respect their independence and that's great, but is there some "issue" that's causing a problem? Can you fix it?
If not, then I think you should just be ready to roll with the punches this Christmas. Maybe be willing to get together the weekend before, for example, if that's the only time all your ac can come. Or perhaps two weeks after. Have a backup plan or something if plans get changed (like a movie you both want to see). Just a couple of ideas, hope they work for you. Hope you have a Happy Christmas, no matter what.
