My wife & I recently experienced this tour while visiting Denali and had a great time. Our guides picked us up from our hotel and drove us out to their Jeeps. We ended up in a Jeep by ourselves and there were six other Jeeps in our caravan. The guides communicate directions & information via CB radios mounted on the dash of the Jeep. It worked just fine and we drove around 100 miles round trip on the old gravel Denali Highway. Rugged vistas, quiet lakes and scenic overlooks along with a few animal sightings made for a great trip. They provided drinks, snacks & a bathroom break along the way. It was a fun way to cover a lot of ground most tourists will not see.
