We stayed at Blue Mounds at the very end of July and it was a great first tent camping experience! We stayed in site 73E which was a little secluded from the rest of the campground but was across from the parking lot.  We stayed on a Sunday night so being at the entrance of the park/across from the parking lot wasn't really an issue at all but I could see if it was a Friday/Saturday it might be.  We only stayed one night so didn't use the showers but the bathrooms were very nice and clean. We weren't able to hike as much as I would have liked but my kids 5/9 still made it about 3 miles on one of the loops and we found our hiking club password. We didn't have any issues with bugs. Luverne is super close and we hit up Tasty's Drive In for supper and it was great!
