I think I'm like most Americans when I say I'm not myself yet in the mornings without my coffee. I had an overall fantastic experience with the company. They were on time picking me up at my hotel. Drove me to the location of the tour without any issues and was simply able to go in and fill out my paper work and check in. However, they give you all of 2.5 minutes to buy, drink and eat your coffee/breakfast before take off. Of course it's not all allowed on the aircraft but I was very unhappy I paid 3$ for a coffee and took 2 sips before I was required to throw the entire cup away.
I was the only one on the aircraft that spoke English, oddly enough and the tour guide didn't make an effort to play the transitions of all the voice videos so I didn't feel like I got the full experience of the history of the Hoover Dam and the Grand Canyon.
I did however got the once in a lifetime experience of seeing the Grand Canyon for the first time from such a spectacular view.
It was a great first experience.
The only improvement I'd recommend for the company is to not make everything feel so fast paced. I felt like the whole tour was rushed completely from one thing to the next. Barely had a enough time to enjoy the canyon walls on the bottom before we had to leave.
