This park makes me think of The Jungle Cruise at Disneyland. It is heavily forested and the sites are literally like threading a needle. Even on the map they look close together chances are you won't really see or hear your neighbors. Bathrooms, shower and dump site available as is recycling and dumpsters. Close to a dog friendly beach but please use the walkways and stay off the dunes. 

There is also a store with rentals and playgrounds available, walking trails and bike trails have limitations posted and entrances so be aware. 

Site have water and electric hook ups but came across a bit of a problem as the outlets are installed upside down so it was really hard to insert the 30amp plug  because the cord made it a very tight fit. (50amp same way) see pictures.

Good cell coverage with AT&T and Verizon.
