At the end of the day...
Safely back at the Green Valley Ranch, the sun was beginning to set and our entire sojourn was a little more than 8 hours and perfectly enjoyable. The time went by very quickly.
There are many optional add-on amusements you can purchase such as a helicopter ride to the bottom of the canyon, horseback rides, and boat rides on the Colorado River. We just didn't have time to try these, but we are planning to go back during the summer for a seasonal perspective and also to review the other amenities after construction has completed.
This tour should appeal to persons of all ages as long as children under 13 are well supervised. All the information presented was in English and I didn't get any indication that other languages were available.
I am happy to recommend both the Grand Canyon West venue and Grand Canyon Express for their excellent service and accommodations.
