The best time to venture into Jackson Hole, I think, is the end of January to the first part of February. It's kind of a down time there, the ski slopes are not crowded, and every hotel has great prices. (Of course, I would never stay anywhere else besides Snow King Resort.) Airlines are cheap this time of year too. Oh, one more thing: go snow-tubing while you are there! Talk about fun! For all ages and sizes, snow-tubing is a blast! And it's right by Snow King Resort (everything is!).
