We stayed at Camper Village in Tusayan, AZ (the town right at the entrance to the South Rim) in January 2015 . . .
Nice campground, but had trouble trying to park the trailer anywhere near level before having to put the jacks under the trailer!
Plus, in January, they had the water shut off as they were worried about freezing, so had to fill the fresh water tank before we pulled into our campsite so we could take showers and such!
Plus, there was no TV reception over the antenna, and the cable TV channels provided by the campground were bad . . . almost non-watchable!
We did, however, enjoy being in town so that we had restaurants, gas stations, gift shops and other amenities close by, that we wouldn't have had if we had stayed at Trailer Village inside the Grand Canyon Park!
Trailer Village had restaurants and gift shops . . . but at a premium price since they were in the National Park!
All in all . . . we enjoyed our stay and am glad we spent the time there!
