Boy...that is a long haul for xmas....mother nature could play a big part in a trip up this way that time of year......If it were me I would fly to Spokane and get picked up there or drive to Idaho from there..........

I made several trips from San Diego to Northeast Oregon (La Grande)
but only a couple in the winter time....most were in the summer....still a pretty long haul 18 to 24 hours of drive time.......
