The site we were in was huge! All of the sites are good-sized. "Clean" does not describe the park's condition: there was a man cleaning the lampposts and hookup boxes every day with some type of feather duster. Incredibly helpful staff. The "highway" is not loud at night at all - there is vehicle activity in the mornings.
This is a great place to spend some time in Newport. It's a nice walk to the marina, restaurants and bars. It's clean and safe. You can hear the sea lions in the harbor. It's not the place for people who want huge sites and lots of park activities. We stay here every year for a week or so (this year for two). The nightly rate is the pro-rated weekly rate.
Bathrooms were clean, as was the laundry: but this place is definitely not a resort. Seldom have I been so close to my neighbors: my trailer's bumper was 3' from the unit behind me. A few sites had tables, we did not.
