We noticed that the buses parked much closer than the cars. Certain advantages are given to tour buses, but we enjoyed the walk and saw lots of wildflowers, so we did not fuss too much! The "bus people" could be a real pain, however. Since they were usually in a big hurry, they were quite pushy. I know that tours are the only way some people can travel, but it sure is nice to be able to stop where you want and stay as long as you want.
