Hotels in West Yellowstone, MT

I'd go the coast. Inland might have chain controls, snow, etc. Fine if you want to stop to ski though. Check Waze etc for closures, chains, etc. The OR coast has lots of great little towns to stay in, and visiting the redwood parks of NorCal is nice this time of year, although damp. Camping on the coast is great this time of year; OR has some parks with yurts to stay in as well, which is nice in storms. https://www.ultimatecampgrounds.com From SF you might want to go down and stay along the Big Sur coast, and then again near either Morro Bay or maybe a campground near Santa Barbara. From there you can go due east pretty much to Mojave and then on easily to LV.
