A word of caution, drove the road from West Yellowstone to Bozeman yesterday and there is a lot of road construction complete with pilot cars and delays. You may want to go through Ennis as an alternate route.
That's exactly right - they are advertising this construction as a 15 minute delay, but it will be much more, depending on traffic and how you hit the one-way cycle.
If you go through Ennis (down the Madison River valley) you will go through the Quake Lake area & monument to get to West Yellowstone. Be sure to stop and review the Quake Lake visitors center, very interesting geological event.
You may want to consider going in the north entrance at Gardiner, ie. through Bozeman on I-90, turn south on Rt. 89 at Livingston, then to Gardiner.
In any case, as others have said, be prepared for crowds in the park. And, if you plan on staying in a campground, be sure to have reservations.
