I stayed with full hookups, but no cable (don't need it, so don't know if it's available) and we weren't close enough to connect to the WIFI (only close enough to occasionally see 1 bar pop up).
Friendly folks, catch and release fishing pond, and a pond with beach for swimming. Good size playground, jump pad, and off-leash"dog park" available as well.
On AT&T, I typically had 2 bars and no problem streaming music or browsing Facebook. My fellow travelers, on Sprint, said they had poor reception. I'm guessing 1 bar.
Worth noting that my wife said the water pressure in the shower house was fairly low. (I shower in the camper, so can't comment.) Water pressure was fine at our site, though. Also worth noting that many of the back-in sites can be pull-through if you get there when it's not busy.
