To really enjoy the canyon we would suggest you stay IN the national park and not try to be by the skywalk which is a tourist trap and greatly overpriced. There is so much to do in the national park itself and is the best way to admire the canyon. There is a full hookup campground, Trailer Village, located near the canyon rim. From it you can hop on a shuttle bus which runs all day along the rim. It's free and you can get on an off wherever you want to explore. There are wonderful restaurants, gift shops, visitor centers, hiking (not only down the canyon but along it for great views), and ranger programs. I think you'd really enjoy your trip here than at the skywalk which isn't even near the major expanse of canyon. Safe travels!
