Newport/Providence RI campground

I will be attending a family wedding in Bristol, RI over Labor Day weekend and am looking for an RV park in the area. Any recommendations??

Really nothing much in this area. Only place I could think of that would be close by is in Portsmouth/Middletown, RI. Place called Melville Campground I think. Nothing to speak of but it is within 20 minutes of Bristol and 20 of Newport. Call early for reservations because they do book up quickly with the Newport festivels.
