I just finally joined this site and saw your inquiry about Pismo Beach, Ca
The absolute best place to stay in Pismo is Pismo Coast Village. It's clean, easy beach access, spacious sites, tree's for shade, quiet and just an overall awesome park. Highly recommend. On weekends it's harder to get in, esp. 4th of July weekend (10 page waiting list) But that goes to show you how nice this place really is. Week-time is easier to book.
Hope you enjoy the park.
