The only thing not perfect about this experience was that I found out the hard way that I get airsick on helicopters. Spent a considerable amount of QT in the Boulder airport gift shop bathroom learning my lesson. @__@
Other than that, this is your best choice for seeing the Grand Canyon from Vegas. They pick you up form any hotel on the Strip, make the journey to/from the airport super entertaining and comfortable, and show you a part of the Canyon most people don't get to see. The lunch was standard picnic fare (sandwiches, chips, etc.) but the champagne was cold, bubbly and generous.
