I booked a tour on 8/20/21 on Trip Advisor for a Lower Antelope Canyon. I was charged 83.00 per ticket. I found out that if I would have book directly with Ken's Tours in would have been 64.66 per ticket. I called National Park Express they said I should cancel and book directly. When I tried to cancel ...they told me no refunds. I never expected to be ripped off by Trip Advisor.
