Yellowstone was a blast for us. We stayed at Canyon Village. Everything to the south of us was bubbling hot water. Gotta see Old Faithful though. North was all the animals. Favorite spot was the Lamar Valley. Whatever you do, get out of your rig. Read somewhere that 90% of people never go more than 100 yards off the road. Lots of stuff to see with short 1/2 mile walks. Above Old Faithful is a ton of stuff to see. Geyser goes off and everyone leaves. Maybe 50 people walk around. Pm me and I will give you my number and we can talk
