The trip, the driver and the guide in antelope canyon were all great. Biggest problem was that, even though Viator had been paid and sent me a confirmation, they never forwarded that to Grand Canyon Adventures (GCA). GCA never called me to follow up, when they saw our name but n payment, so when we arrived, we almost couldn't go on the trip. As this was my wife's birthday present, and had been on hold for over a year due to COVID, we were about to have a problem. If another couple hadn't cancelled that morning, we would have been stuck. Not a good communication ob by either company.
