Any thoughts on Mather NPS campground? Trailer Village RV Park looks like a big space assigned parking lot which doesn't really appeal to me.
Mather's is mainly tent camping, while Trailer Village is full hook up. While Trailer Village is basically a parking lot, the location is terrific and you also get visitors to the campground like this:

This was taken during our last stay.
We've been to both the north and south rims. Bot are BEAUTIFUL, but our preference is the south rim. You won't go wrong either way. The crowds aren't too bad, the Grand Canyon Village area at the south rim is very interesting, and if you hike a bit away from the central area, there aren't many people around. In addition, hiking the Bright Angel Trail and the other trails are fairly empty.
