Driver/guide was very knowledgable, polite and helpful. Minimal wait times for shuttles. Almost 1/2 hour wait for the skywalk. Unfortunately, A/C was not working and half way to the canyon, we were told a new bus was coming and we had to wait 1 1/2 hours for the new bus. While the air worked on the new bus, it was so loud, it was difficult to hear the guide. Also impacted our time at the canyon (only 2 3/4 hours). Good pick-up and drop off. Asked for gluten free. Could only eat banana and oj for breakfast (also given muffin and crackers). Lunch was supposed to be a salad (instead of sandwich) with turkey but only had a small portion of shredded cheese. Included a cereal bar. So if you are gluten free, bring your own food.
