The list of amenities can be so broad my guess is it's going to boil down to what you can afford to build in.
I would say flare out the ends of the spots where they join the campground road and have no roadside trees, bushes or big rocks where trucks are going to be backing in.
One of my favorite campgrounds has narrow roads and a big rock right where my front bumper needs to swing when backing in. Another site has a rock on right at the front right corner of the site. So you can't see it when backing in and it can hit the side of a trailer and do some damage if the driver has a poor spotter.
Oh and if you have the room, flare out the pads at the roads. Don't make people back in around a 90 degree angle with curbs adding to the complexity. Flare he entry wider to make it easier to cut the corner when backing.
