Not quite glamping, but close...
This is a great campground for families with young kids. The sites are nice and big, and you don't feel like you're right on top of the people next to you. They are also well shaded - we were there during a heat wave, and we were able to stay cool under the trees. You are a short walk down to the lake from pretty much anywhere, and there are a variety of different beaches. There is easy access to clean bathrooms with sinks and toilets, and there are even coin-op showers.
