In mid-September of last year (2019), we spent four nights at Beverly Beach Camptown RV Resort in Flagler Beach, Florida. We were in site #63, with our front windshield only a few feet from the seawall and the Atlantic Ocean. I should also mention there had been a significant storm in the general area a day or two before we arrived, so the ocean was pretty rough for most of the time we were there.
The view was great, the site was insanely expensive, and the salt spray was terrible. I hosed down the front of the coach at least once a day and it still looked pretty bad by the time we left.
It was an interesting experience, we met some very nice people, and thoroughly enjoyed the area and our time at the RV park. That said, I would never do it again. (And that's coming from a guy who grew up in a southern California beach town.)
