I like the tour the the fist guide was really good, the guide from the secund day, was ok, I didn't like that he didn't translate everything he was saying into English as well, he would take 5 minutes on Chinese and 10 seconds in English. Besides that everything was good.
Good tour. Just be aware that the posted price does not include all the mandatory fees: 1. Service fee for tour guide and driver was $24 per person for the 3 day tour 2. The grand canyon IMAX & lunch was not optional and was 25$ per person (so the total for Grand Canyon south rim was $75 per person)
