Thank you for the additional replies and info. My partner does have a handicapped hanging placard. And yes, over the past few years, our method of trip planning (or not planning) and camping has definitely changed. I just really wanted to know what the game plan is for the non-reservation makers when their chosen campground is full. Pertaining to Bakers Hole, well, 2gypsies has indicated we will have a slim chance in the summer to get an electric site. So I guess I'll just go ahead and make reservations somewhere else in or around West Yellowstone.
