best place to stay when visting yellowstone

For full hookups inside the park, it's Fishing Bridge or nothing. Lots of other CG's within the park but no utilities. Many here on the Forum don't like Fishing Bridge for its lack of ambiance. IMHO that's not the point - there is way too much to see in YNP to hang out in the CG for extended periods. Also, we found Fishing Bridge to be about as centrally located as you can get. You'll still rack up a lot of miles seeing even only the major tourist attractions. Make sure you have lots of food & supplies before you enter the park, as well as a good level of LP gas and warm clothing. Temps in the 30's at night even in July are not unusual. Enjoy & safe travels.
