Campgrounds are kinda like RV's, there are alot of variety. Popup vs Class A, and boondocking vs resorts. I've never booked based on WIFI or cable, and we don't have a satelite for the camper. If they have it fine, but not something we look for.
I also think if depends on how long your trips are. We both work, so we camp on weekends, and a couple of week long trips a year. We are trying to get away from things and explore.
I think if are a snowbird, or full timer, then these things may be more important to you.
It is nice on rainy days, or at the beach in the middle of the day when it is blazing hot outside :)
