monterey and carmel

You could try the Moss Landing KOA. It's a bit pricy and the sites are a bit close together, but its about 30 minutes north of Monterrey, very clean, and very quiet. It's also big rig friendly.

Also, within walking distance is Phil's Fish Market and Phil's Snack Shack. Great seafood, and great breakfast/lunch offerings. The Snack Shack opens very early as I recall.
