Tips for camping with families

Tips from RVers
Site selection: Choose locations based on rig size and hookup needs. "Heads up, big rig owners! Our Pull-thru FHU Patio site had a serious slope. It was impossible to level my 45' motorhome without elevating the front wheels dangerously in the air," warned a Harpers Ferry KOA visitor.
Utility availability: Water and electric hookups vary significantly by campground. A Little Bennett camper detailed: "There is no satellite coverage due to the heavy tree canopy. OTA TV was descent using an external omni antenna. There is no WiFi."
Road conditions: Some campgrounds have narrow or poorly maintained access roads. At Brunswick Family Campground, a visitor noted "the road into the campground was badly in need of repair."
Cell coverage: Service varies widely throughout the region. A camper at Little Bennett reported, "AT&T 5 MB/s w/o booster (1 bar), 8 MB/s with it (2 bars)," providing useful connectivity information.
