For our stay, we had two campers and two tents. We stayed for three nights, all below 32 degrees (the tenters only made it the two 26 degree nights) over Thanksgiving 2018. The waterfalls were awesome, especially with the enormous amount of rain we had the previous week. The pavilion and cooking area were more than adequate. The supply of dry firewood is provided by the owners at a minimal cost. The fire ring was a great size... the area could seat any size group, depending on how roomy your camping chairs are, and had a table and a few benches provided for your use. The restrooms were clean and the "girls" side had a heater, which kept it nice and toasty.
One negative (which was unavoidable) is that they'd had to winterize and cut off the water to the pavilion area. We bought water jugs and toted water up from the restroom area, not a huge deal. If only the restrooms were closer to the pavillion.... we had to keep driving my elderly mother down to use the facilities throughout the day.
Also, next time we stay we will know how to pack the pavillion stuff, so that it will not require extra shifting and transporting. Campers that need to use electricity will be at a bit of a distance to be carrying things back and forth. Pack items in your vehicle to save energy.
