Absolutely loved it! took the canyon tour/w lunch. From the limousine pick up at the hotel, to the greeting at the counter, to the pilot Jon- the customer service was flawless. Everything was explained to us safety wise, the earphones w/ headsets and music were great and so was the narration. We booked through Viator and that was simple and effifient process. I definitely would use Viator and Sundance again. The lunch in the grand canyon was very nice- champagne and sandwiches. the entire experience was completely fun, very safe and an all around great time. Its a once in a lifetime memory, and I would strongly suggest taking this flight!
