We have been staying here for a few weeks now. It is in a spectacular location, and all the facilities are new and well-maintained. The internet speeds nearer the quiet highway are more than sufficient for online gaming (yeah, we do that). Fairly handicap accessible. The pads are gravel, but the roadways are all cement, the bathrooms have wheelchair-accessible showers, and the swimming pool has a hoist so that folks with physical disabilities can safely enjoy the pool. I haven't seen an RV park with one of these before!
AT&T has, by far, the best connectivity here (T-Mobile had no service that I found).
Close to Zion, on the way to/from North Rim of the Grand Canyon, near Coral Pink Sand Dunes State Park, Page Arizona and Lake Powell, Kanab Utah… Heck, the whole region is spectacular. I recommend just sitting in a camp chair at sunset, having a drink and watch the sunset set nearby Smithsonian Butte aglow.
One other note: Dan is the owner. Super nice and friendly guy, and he works his butt off keeping this place nice.
