We stayed in Grand Canyon last year in Early Feb. We ended up staying in the "rv" style campground. The smaller Mather campground was open but only a few spots were plowed and none could accommodate our TC. We ended up staying at the "trailer village" campground while they were in the process of plowing spots. I would call the park and see what the snow conditions might be. Other than that we lucked out with 2 clear sunny days which took the chill off. Very few park visitors which was awesome. Definitely would do this again.
Here is a shot from the campground with some wildlife.
