If its an FAA PPL you'll probably have to find a school or club, take a fly in one of their aircraft to get checked out, and you'll be sweet. There is, if I recall correctly, a small airport at the south rim of the canyon, but mind your ps and qs around the canyon itself as its a noise sensative area and I'm sure there are special procedures and restrictions on flying over in a lighty (as well as the fact that in November the weather is likely to be a bit shiite).
If this doesn't appeal to you (cost, license issues, etc) I'd recommend driving to the South rim of the canyon. Its a bit of a long haul, but VERY beautiful and worth a day or two of your holiday (drive out in the morning, stay the night at the canyon, and return the next day).
Hope this helps you a bit.
