We camped in site 103 and found it to be an awesome spot. We brought our infant for her first camping trip and from 103 you couldn't really see anyone else's camp site (site 102 was across the street from our spot but no one was there). It is also nearly as close as you can get to the beach and has quick access to shower/bathroom and water. 

Only downside was that while It was quiet at night, during the day you are near the entrance so there was a lot of foot traffic and cars/RVs driving through. It didn't bother us though.
