Dual enrollment summer school with "liberal" rules

My son will be a rising senior next summer and wants to take four college classes in summer school. He’s got several options.

First, he can just live at home and attend Ole Miss classes. Second, he can sign up for the Ole Miss High School summer program, where he will live in a dorm with other high school kids. However, the program is pretty much like a prison, with the kids restricted to campus, not allowed to use their cars, and a 9:30 curfew every night. He will not want to do this. Third, we can find a program somewhere else with more reasonable rules.

In poking around on the Internet I found that Standford has a program that essentially treats the kids as college students with some additional supervision, but of course it costs a fortune. Others seem to have more relaxed rules, but just barely. But I really don’t know for sure which schools even have these summer programs. Any thoughts? I’d love to get my son out of the house so perhaps my wife and I could go away somewhere, but he doesn’t want to go to jail.

BTW, when my 17-year-old son starts his senior year he will be as old as I was when I went to college. Several of my fraternity brothers also started college at 17. The idea that we have to treat these kids as little babies in diapers rather annoys me.
