I appreciate the feedback on these local campgrounds. While Acton would not be a destination for me, the location could be good for overnight on the way into southern CA-somewhere to stay waiting for favorable traffic conditions.
Between this post and the rvparkreviews it doesn't look too appetizing. OP should write to KOA headquarters-citing the noise and that advertised facilities were closed to most campers. Parties are fun but there are times I need to sleep too. I don't want those terms dictated to me.
