My goto place is
Flory's camping.
It is quiet and right in the middle of Amish country. Right down the street from Bird-in-Hand. Been staying there for years and if you are looking for just a nice level site with good wifi this is the place we call home.
Before I get hammered.. let me state the following.
They do have some long term construction guys in 5th wheels... They are quiet and never around much. And like I said they have good level sites to park your rig, very clean rest rooms, great wifi, a great place to explore the area.
