We arrived on Thursday evening. After a short debate we opted to pay the extra money for an electric site - based solely on the fact that the water wasn't turned on in the basic site loop (we later discovered it was also off at the swimming beach).
At a guess the basic sites aren't used much as they seemed less kept than the electric sites. Finding a place to pitch a tent in the electric loop was a challenge but we did find one that had enough level grass. Site 4 - close to the water spigot and a modest walk to the bathroom/showerhouse.
Though it was definitely busier come Friday night not all the sites were full and most seemed to be retired or semi-so with grandkids. No party atmosphere - which is what we happened to be looking for this trip.
A nice, quiet place to spend a weekend away with Amish country store a close distance by.
