We stayed at one of the Premium Waterfront sites in early April and absolutely loved it! It looks like many of the people here have year-around rentals so I would imagine if you are booking throughout the summer, you'll want to get your reservation in as early as possible. Having a picnic and campfire area right next to the water was a unique experience for a campground and we would definitely stay again if we are ever in the area. One thing you will want to note is that you may need an electrical extension if you're bringing a towable as the electric is on the opposite side from the sewer and water. The campground does have a supply of these, if needed. Oh, and the wireless can be spotty depending on your site location in the park.
I would give this place 3.5 stars for the visual atmosphere, however, given the noise levels from the interstate and highway, I can't give it four. It has lots of trees but they don't seem to do much to block the constant noise. I did like the contactless check-in. I would stay here again for one night in a pinch but would not enjoy being here long-term.
