Can you start new traditions with your kids? Bake together. Or, spend the whole day in your pajamas just playing games, reading, etc? When I was a kid, we always opened our Christmas presents on Christmas eve, that way we could sleep in Christmas day. Then, we spent the day in our pajamas, playing. Now, we usually go to the inlaws on Christmas Day, but my favorite Christmas's are the days we stay home playing games and watching movies with the kids. If the kids are going to be at the x's on the actual day, celebrate on a different day. Then, on the actual holiday, make it an all about you day - do whatever you want. Go to a movie by yourself, volunteer at a food bank, spend the day in bed with a book (what I'd do), meet a friend for lunch at a chinese restaurant (seems like they're always open on holidays), etc.
ETA: Sorry, looks like I was the one focused on the actual holiday. Apparently, my reading comprehension is not so great today!
