I will take a look at prices for you if you can provide me with dates. I actually worked in LAS
and sold many packages to the Grand Canyon for different companies. If your feeling adventerous, and want to pay a few extra bucks, I would suggest the helicopter tour! That was an experience I will NEVER forget.
Heli USA was once able to land next to the Colorado River, and the pilot would serve a champagne brunch! I took that tour, and was amazed. They state they will go 1500 feet below the canyon rim, so that is still an experience in itself. The chopper ride is smooth, and awesome. The pilot will sometimes do some fancy tricks for you.
Scenic is also a treat. They fly the Twotter, and that would be a fun experience for you. Eagle/Scenic used to fly the F-27, but I have not seen them anymore. Maybe someone can open the can on this question.
Well worth the visit. The Grand Canyon looks like a hole in a picture, but unbelievable in person. I about urinated myself when I looked down from the rim of the canyon. Not recommended for anyone afraid of heights! LOL!
