We had a great time at this campground...some excitement the first morning as a young grizzly wandered into our campsite and we had to back into our camper and rooftop tent.  Host security and rangers were very helpful.  Facilities were clean.  Note that there is no cell reception.  Conveniently located between the Tetons and Yellowstone, but be prepared to do a fair amount of driving to see attractions in either park.  We had a site on the perimeter, but depending on where you are I can imagine some of the sites are a bit close together.  Site sizes vary, but some of the fifth wheel folks took quite a while to maneuver in and out of their camps as things could be tight.  Staff was helpful, and the lodge is close by for food and supplies.  Lodge has free very spotty satellite wifi if you need internet access.  4 stars instead of 5 because depending on your campsite location there is a fair amount of highway noise.
