Not sure of your travel plans but just off I-74 near Batesville,In, which is not as far off the interstate as Sunman there is a Thousand Trails Park called Indian Trails. Rumor has it that KOA is some how involved in it's operation now. They do have a section of full hook up but they do fill up quickly. The park is huge and most sites are electric only. I had stayed there a few times but felt it was not "up to par". but would be a ok stop for over night. I would think it's a much easier in & out than anything in Sunman. I have not heard of Lake in the Pines . Indiana State Parks have a good reputation , but Versailles is a good distance from I-74 if that is the route your traveling.
