We were picked up promptly at our hotel at 8:15 AM, and driven to lower antelope canyon first. Our guides on the van weren't the ones who took us through the canyons, but the tour guides Dineh hired for us to walk through the canyons were excellent. After a 90-minute tour of the lower canyon, we drove to the upper canyon and were escorted through for a 60-minute tour. Every tour guide we had that day was Navajo, which absolutely enriched the experience: Who better to learn about this land from than the people whose ancestors lived here thousands of years ago?
The only reason I'm not giving this tour 5 stars is because the upper canyon was almost entirely dark. Given the cost per person of this tour, I was really disappointed to find that was the case. I don't think that tours to both canyons should be offered during the off-season/when virtually no light reaches the upper canyon. Would absolutely recommend this tour to others, but with that caveat.
