My X and I alternate everything every other year except Xmas eve and Xmas day. She always had the kids xmas eve. They did the mass and dinner and opened gifts that evening. Santa showed up while they were at mass. She would drop the kids off at my house at 9AM. Santa left gifts at my house as well. We would open gifts in the morning and have dinner 2pm ish.
I guess my point is some things do not have to alternate. Some things can be done without being together. Figure out what works best for the two of you and your kids.
