We faced the same type of dilemma after we moved from Houston to San Antonio. Be the parents. Be the adults. Do what is best for your family and cheerfully say that anyone is welcome to join you. Period. End of story.
Personally, we stay home on Christmas and Thanksgiving. We want our kids to remember traditions in our house, not scurrying around to be at someone else's house.
