However ... a much different kind of "scenery". If you are like alot of drivers, it seems you are already late so must speed recklessly. On the other hand, if you can be calm and just enjoy the scenery, wildlife, and fresh air, then a leisurely visit through Yellowstone is well worth your patience. The speed limit is 45 mph ... but that's way too fast.
Best advice is to endure the traffic, crowds, and elk & bear jams ... to view the iconic wonders of the Park, then find trailheads, park your vehicle and get away from the traffic and you will be delighted at the backcountry features. My definition of a good hike in Yellowstone is that once the noise of screaming Harley motorcycles is no longer heard ... it's a good hike!
As far as where to stay ... if you have a large budget, then stay at Lake Hotel or Roosevelt Cabins. If camping, try to get a spot at Pebble Creek CG in the Lamar Valley, Mammoth CG, Norris Jct CG, or Lewis Lake CG. Outside the Park, campgrounds near Cooke City or such as Eagle Creek CG or others on the North Fork of Shoshone out of Cody are good. But you may need a hardside camper.
Best advice when beginning your visit is to get good maps and to visit interpretive centers. The one at Mammoth will provide a wealth of information.
