Although its not in Pismo Beach, Morro Bay State Park is not too far away. Most of the the dry camping spots are pretty spacious and there is a dump station on the premises. There are some sites with partial hook-ups but in my opinion, those are narrow and a little tight. I'm not sure exactly what they offer, but the park has a small marina right across the street from the campground. I know there is a restaurant there, and I think they might also rent kayaks there. The campground is situated on a scenic old golf course very close to the ocean. The town of Morro Bay is very quaint with lots of shops and restaurant and a spectacular view of Morro Rock. Its within walking distance of the campground (about a 10-15 min walk.)Check it out.
