best place to stay when visting yellowstone

Our first trip to Yellowstone was last summer and we stayed at Fishing Bridge. Our site wasn't very good...small by even Fishing Bridge standards. But, the location is good for seeing quite a bit of the park. If we ever return, I wouldn't stay at just one campground, but spend a few nights at Fishing Bridge, and then move to a different location either at the western or northern entrances. We didn't really get to explore around the northern entrance but it looked really interesting when we passed through.

And, if you haven't been to Grand Teton NP, don't miss it! We had a great time there.
