I am so sorry to report, I haven't been to Biloxi, Ms., since the 80's. Catpuppy goes frequently, I think. I'm pinging him for his input. :)
Heyyyyyyyyy Catpuppy, smooch.
I often stay in Biloxi as a convenient and reasonable stopover when headed west. There are nice hotels with good food at the casinos. Biloxi and Gulfport and Bay St Louis also have top entertainers whose shows are comparable to those in Las Vegas.
As for the camping and the beaches, I haven't a clue other than to say that I noticed no damage to the beaches when I last was there a month ago.
