As usual, there's a bit of deception in this add, as is often the case with grand canyon west tours of any kind. The photo of the airplane shows scenery that was photographed farther esat and north of gcw in the Grand Canyon near the South Rim, not the scenery at gcw. GCW is a scenic place, but it's just not the same as the GCNP at the South Rim.
For the fees promoted in this ad ($177.00 for 2 people) you could rent a car and drive to the Grand Canyon Nat'l Park at the South Rim and spend a full day and possibly even stay over night. It would be a much better investment of your time and money IMO.
