Tons of empty campsites of various sizes in this campground, on a weekday in late May. Over 300 sites total, 22 bathrooms, everything on a first-come, first-serve basis (although you can rent the RV sites). Didn't stay overnight, but it seems like a clean, well-run federal campground, so probably getting to sleep by 10 and being up by 6 or 7 and you've got yourself a good night's sleep. Should be able to find a site on most nights, and well worth it due to the open feel, fresh air, lots of mini-trails and roads to explore, huge variety of campsites and sizes, lake and mountain views (sorry they didn't show up well on the video) and of course its proximity to unlimited hikes and sights in the Grand Tetons and Yellowstone national parks.
