We just picked up a cancellation on a Rim Side Pioneer Cabin for 2 nights the first day of our trip. This works well for our group (3 adults + 2 small children) and for our itinerary (North Rim Grand Canyon, Zion, Death Valley, and then Las Vegas) but I have a couple of concerns.
1) Our flight lands around 3 PM in Las Vegas. So we will arrive around dark since it will take some time to get the car and we will stop and eat somewhere. How is the drive at night? I know in Yellowstone, driving at night was highly discouraged.
2) Coming from Central Kentucky (elevation probably 500 ft or so) - how likely are we to have trouble with altitude sickness since we will be starting the trip at with a night at the North Rim?
If we are lucky enough to find another cancellation another itinerary could be Zion, Grand Canyon, Death Valley, and then Las Vegas. That would give us some time to acclimate at Zion. But I think the drive from the North Rim to Death Valley would be pretty tiring in one day.
