We spent 8 days here for a vacation.  The sites are small, but level and include FHU's and cable.  It was very crowded, but still relatively quiet.  A lot of winter Texans spend the season here, as the weather is really nice in winter.  There are not many places to walk your dog, but they do provide waste pickup bags and there is a small dog park.  The campground is right on the bay and there is a wonderful restaurant on a pier that is walking distance.  You can also take tours of the bay via boat here.  The county beach is pretty close, and you can walk or ride the free city bus to the end of the line (a few minutes ride) and get off and walk to the beach.  Very nice beach with modern facilities. You can also take the free city bus (bus stop is at campground entrance) into S Padre island or over the bridge to the mainland.
