I don't have children, both my parents are deceased and one of SO's parents is deceased and the rest of his family still live near each other in suburban St Louis except his two nephews, who are still in the young adult not married phase of life so they still go to St Louis for the holidays if able. My sister and her wife are in San Diego. As such we've spent a lot of christmas's in St Louis and a lot of Thanksgivings in San Diego. Relatively simple and enjoyable as I get along with his family and SO adores my SIL. (He gets along with my sister but pretty much everyone thinks my SIL is AWESOME. And she is. Such a kind, sweet woman. My sister is incredibly lucky (and knows it) to have her in her life.)
Back when my dad was still alive he didn't travel so it was common for us to spend thanksgiving in Denver with him, going out to his favorite restaurant for dinner. I agree with the comment that it feels kind of festive to do that. The staff always seemed happy to be working and all the other customers seemed happy to be enjoying their meals together. And no cooking or cleanup chores. I totally get why people go out for dinner on the holidays. This year we're going to St Louis for Thanksgiving and staying home for Christmas so we'll probably eat out for Christmas, which is fine with me.
I guess I say all that to say that I agree with Iris. Find a way to enjoy the holidays that gives you peace and contentment rather than stress from changed plans and long days driving somewhere you don't want to go. And holidays are overrated. Use other "non-special" times of the year to get together with the grandkids so that you have a good relationship with them. When I was a kid every August my favorite aunt invited me and my sister to come for a week during the county fair in her small town. It was nothing fancy, lots of 4H kids showing off their work raising animals and such, and a small rodeo, etc. But we went to everything and it was always a really great trip during a random week in August. Honestly I can't remember most of the MAJOR HOLIDAY stuff my family did because it was things like spending the week at the county fair, or the time that just she and I went to Mount Sunflower, the highest point in Kansas, that really built my fond memories of my aunt.
