that's not camping, that's a wallless hotel, lol.
If you are bringing kids and wife, be prepared to have an excess of stuff you won't need and barely the room for it.
Just bring the basics - tent, sleeping bags (air matress), food, drinks, cooler, trash bags, matches, radio, flashlight/lantern, folding chairs, rain poncho, toiletpaper, 1st aid kit, towels, soap, bug repellent, and possibly some cards/board games to entertain.
