ya going to the canyon from vegas HND is the better choice.
There are 3 or 4 tour operators flying out of VGT to the canyon, flying
out of HND you dont have to talk to anyone going to the canyon.

Consider HND Henderson rather than VGT in Las Vegas. They are
about the same distance from LAS but I think HND is easier to
get out and over to the Grand Canyon.
