The GC national park is only a small part of the grand canyon.
I’ve worked on both rims of the park.
The folks who go over to the ‘indian’ side rarely walk more than a half mile from whatever transportation gets them there.
And the native american hosts charge an arm and a leg for that experience.
The park will be just fine.
The south rim of the park gets about 4 million visitors a year. 99% never go below the rim.
The north rim gets only a half million visitors a year. (only open may to october) and less than 1% go below the rim.
The only thing the build up of the native american side will do is relieve the overcrowding at the south rim hotels and eateries.
BTW, when the Grand Canyon Lodge opens each spring it is 100% booked for the entire season. Many make reservations 18 months in advance.
They sure do...I think it costs $80+ a person for the Overlook platform, and I don't believe you can take your own pictures.
