I quit the travelling thing once I had kids. Most people do. It's like you said, the preparation to get there, the stay, the drive home, the unpack...... its flippin exhausting and really takes away some of the "JOY" of the season.
I would now start the "new tradition" for your little family. You do NOT have to be somewhere visiting on the actual day of the holiday. The season is lengthy enough to fit visits in where they are comfortable. We did most of our out of town visiting AFTER Christmas day and BEFORE New Years Eve. The traffic isnt as bad and you have the story to tell of how Christmas morning went at your house this year. The family will live without you. When the kids all get much older and you all agree that Christmas morning is no longer the giddy, exciting, fantasy filled, Santa bash that it once was, you can then choose to go back to some of the old visiting traditions of the past. I never did tho.... I never looked back, we were always home on Christmas morning and I would not change that decision if I were to have a do over.
Make new traditions for your family. Cut the strings that bind and suffocate. I'm sure if you ask around, most of your elders did the same thing when their kids were little. It's just too messy to do all that travelling. It's way fun to get packages in the mail and cards and phone calls tho.... nothing wrong with that!
