We stayed at Ellie's Favorite, campsite 5, and had a great time. There was plenty of room for our car, three tents (and maybe even a couple more, as well as for us to spread out.
A few things to note: there are no picnic tables and the ground is dirt, so you will definitely want to bring chairs and a table of your own. The river is just a very short walk away and was low enough to set our chairs in and enjoy the scenery. We saw some other campers fishing up stream.
The entire farm is beautiful, and we took multiple walks around the fields. Note that while the campsites are far enough away that you can't see each other and won't overlap much, we did hear children playing/screaming and music from another campsite. Also, the site is very close to a major highway so you will hear the buzz of traffic throughout the day/night.
