Lebanon Hills is closest. The sites are large and widely spaced, and there is coin laundry on site. It's popular with large class As for 1-2 week stays. The only real drawback is that they do not have full hookup sites.
The closest campground that I could recommend that has full hookups is Shakopee Valley. I have not been to the St. Paul East KOA which reportedly has an unusually strict 9:00 p.m. gate closing policy.
