We did what I called the "Big holes in the ground tour" two years ago, which included the Caverns of the Grand Canyon, the Grand Canyon south rim, Meteor Crater, Calsbad Caverns, and White Sands Missile Range (where I served in the Navy).
We also took in the Painted Desert and the Petrified Forest which are next to each other.
At the south rim, we took the train from Williams, then stayed 2 nights at the GC, then back to Williams. Using the shuttle, we saw just about everything there was to see, short of hiking down to the river.
