Small group of 8 meant that the guide could tailor the trip somewhat. For example, he gave me longer than the others to hike into the canyon and even dropped me off at the trail head. The tour guide was entertaining and knowledgeable. All in all, a wonderful tour of the canyon with 4 different views from the middle of the south rim to the easternmost point. The stops after the canyon were not that great, but I just viewed those as a bonus. 5 hours at the canyon was enough for the first time.
