If you’re wondering whether you should book or not, just do it! Ray’s was everything I needed and more for my three-night trip visiting NRG. I stayed in the Kentucky cabin which had 2 bunk beds, larger bed (full or queen?), nightstand w/ light, extension cord, standup heater fan, ceiling light/fan and trash can. There was a porch with a picnic table and two additional wooden chairs. There is also a fire pit.
In the common room (quick walk from the cabin) there’s a living room with TV, sofa, board games and more. There's a kitchen with a fridge/freezer, stove, oven, sink. There’s a large covered area off this common room that has a grill, tables and chairs. Next to this area is a small open shed that has ice $2 and firewood $6 or $7 if I recall.
On the opposite side of the campground (still a quick walk from the cabins) theirs is a large outdoor utility sink and cabinet, and a washer/dryer that is $2/ea under an awning. I didn’t use them so I’m not sure how you pay. There’s a separate men’s & women’s restroom/shower. I believe there were 3 showers and 3 toilets in the women’s room. The showers had hot water and the utility sink was super convenient for washing dishes.
I have AT&T and had 2 bars everywhere I went around the campground. After each day of hiking from AM to PM, the Kentucky cabin was an absolute oasis. Especially after ending a long roadtrip of camping in the rain!
