Friends of ours manage this park for the summer and we decided to visit and stay with them before we head to Boulder, CO for some concerts. It seems to be a mostly transient Visitors with 1 or 2 stays after coming from Salt Lake , Grand Teton etc.
It is a functional Park, with a big playground, large dog park, go kart rentals, miniature golf, courtesy car,laundry facility and nice clean bathrooms.
Verzion and AT&T have great coverage T-Mobile is dead but suppose to be roaming on another carriers network. The park itself offers wifi which is of good quality.
