Thanks, Julius for the info. I guess I'll try to do a lot of online research. Anyone know if this will work? Arrive at South Rim and camp one night (Where?) Leave car(s)(Where?) Take 7:30 AM shuttle to North Rim arriving at noon. Have lunch somewhere then head down trail and camp one night at Cottonwood Campground. Next day hike down to Bright Angel Campground. The next day hike around near BA Camp. (Should I camp more than 2 nights here? Are there many day hikes in this area so that I would want to camp more nights here?) Next day hike up to South Rim. Camp one night at South Rim (Again not sure where. Can I park and leave my car(s) at a campground on South Rim?)
