Took my wife there last year for her 40th and had a great time. we went on one of the helicopter tours and had breakfast at the bootom of the canyon. It was amazing. They picked us up by Limo at the hotel and took us to the airport. the flight there is about 50 minutes , you spend about 30 min on the floor of the canyon and then about a 45 min flight back with a tour of downtown Vegas. Very expensive, but worth every penny.
have fun
