To think it would be nice for them to come to us for once

Sorry, I do think you're being a bit unreasonable here. It's fine to suggest it but they aren't obliged to come. It sounds like they visit you twice a year, which is a decent amount considering you live abroad. You're suggesting they are chosing your siblings over their grandchild, but that's probably not how they see it. It's likely in their eyes they think they should spend Christmas with your DB as he doesn't have a partner, whereas their grandson has you and his dad, and you all have each other.

Because you chose to move abroad.

Why don't you invite your siblings too and have a proper family Christmas without enforcing a separate Christmas for everyone?Probably too late this year but consider it for next year?

You mention sun and walks - we can do that all year. At Christmas, I want cosy and cold and English festive traditions. It may be there is more than just family reasons that's putting the off, I'd hate to spend Christmas abroad - maybe they would too?

your parents sound very similar to my mother on this. Two of my siblings live in different places. She visits them throughout the year, but at Christmas she declines, and just opens her to any us who chose to visit. She won’t travel to one ‘child’, because that means her actively choosing not to see the others. This way we decide whether or no we see her, rather than (in her eyes. We’ve all said we don’t care) her choosing a ‘preferred child’.

It always surprises me when people move far away or abroad and then get frustrated when people choose not to travel to them. You chose to move away OP. Maybe your DP don't want the expense of having to travel to you. Some people are set in their ways and your DM obviously likes having all her family around at Christmas. You moving away has made that awkward to achieve.

Does your DH not have any family who want to visit or spend Christmas with you?

At least it sounds like they share the travelling generally OP (you travel twice a year and they travel twice a year). I think lots of families would expect you to do more of the travelling as you moved away.

@Doghatestherain I was coming on to say quite the opposite of this really but it’s actually just proving my point. People think they’re just because you choose to move abroad that it’s therefore your problem to make the contact and to come home to visit people but it’s really a two-way street. It’s not an expectation for anyone, but you made the offer and she has said no (or at least you think she’ll say no) that is not your problem to fix. Just because you moved abroad doesn’t mean that she gets to guilt trip you into coming home every Christmas. Go home if you want to go home stay where you are if that’s what you want to also, there is no right wrong! And the sooner you realise that you can let all of the emotions associated with it the sooner you’ll make a decision that suits you best.

It would be nice and you should definitely suggest it, but I also don't think you should have any expectations that anyone should visit you since it was your choice to move abroad. You also aren't obligated to travel to them either.

I don't think it's very fair to move abroad and then decide that other people have to travel to you. Surely if you go back you can enjoy time with your siblings as well as your parents?

Just don’t go. Stay home and have a nice Xmas with yourselves.

Let them! There is no need for you to take that on. stay home, let your DC wake up in their own home, have a lovely relaxing day as a family unit, enjoy the walks and quality time and ultimately save the money and the hassle ! I know I would

YANBU to suggest it and invite them, but as they've said no, then obviously you can't make them come. So I guess you either travel or you don't see them this year.

Then stay home…you don’t HAVE to go home. Give yourself a break.

edit it to actually answer your question, but yes, it would be nice for them to visit you but I have a experience in this and they won’t because they don’t have to and they know that. I say stay home then next year they might come to you.
